Not really.
It would be just be the new match_string() helper/macro in a new commit.
And the conversions of the simple users of match_string() (the ones using
ARRAY_SIZE()) in another commit.

That would break the build, why do you want it split out? This makes
sense all as a single patch to me.

Can you split include/linux/ change from the rest?

There is no need for NR_PHY_TYPES now so you could remove that as well.

I was trying to avoid having to change the prototype again in the future, but it's not a big deal, if enough work goes in to require more than 32 bits, it can be updated at that point.

I'll wait for more concrete criticisms here, this it a bit too vague to take any action on.

Calling hexdump (even in it's unaltered form) in performance critical code is always going to suck. As you mentioned before, it's all based around printf. A performance conscious user would be better off building their code around hex_asc_hi/lo instead (see lib/vsprintf.c:hex_string).

* [PATCH 01/16] lib: fix match_string() helper when array size is positive

The documentation the `_match_string()` helper mentions that `n`
(size of the given array) should be:
* @n: number of strings in the array or -1 for NULL terminated arrays
The behavior of the function is different, in the sense that it exits on
the first NULL element in the array, regardless of whether `n` is -1 or a
positive number.
This patch changes the behavior, to exit the loop when a NULL element is
found and n == -1. Essentially, this aligns the behavior with the
doc-string.
There are currently many users of `match_string()`, and so, in order to go
through them, the next patches in the series will focus on doing some
cosmetic changes, which are aimed at grouping the users of
`match_string()`.

The change is purely cosmetic at this point in time, but it does highlight
the change done in lib/string.c for match_string().
Particularly for this change, if a regname is removed (replaced with NULL)
in the list, the match_string() helper will continue until the end of the
array and ignore the NULL.
This would technically allow for "reserved" regs, though here it's not the
case.

the change done in lib/string.c for match_string().
Particularly for this change, a control mode can be removed/added at a

This change is a bit more than cosmetic.
It replaces 2 values in mtrr_strings with NULL. Previously, they were
defined as "?", which is not great because you could technically pass "?",
and you would get value 2.
It's not sure whether that was intended (likely it wasn't), but this fixes
that.

The `device_connection` struct is defined as:
struct device_connection {
struct fwnode_handle *fwnode;
const char *endpoint[2];
const char *id;
struct list_head list;
};
The `endpoint` member is a static array of strings (on the struct), so
using the match_string() (which does an ARRAY_SIZE((con->endpoint)) should
be fine.
The recent change to match_string() (to ignore NULL entries up to the size
of the array) shouldn't affect this.

The `armada_37xx_pin_group` struct is defined as.
struct armada_37xx_pin_group {
const char *name;
unsigned int start_pin;
unsigned int npins;
u32 reg_mask;
u32 val[NB_FUNCS];
unsigned int extra_pin;

};
The `funcs` field is a static array of strings, so using the
new `match_string()` helper (which does an implicit ARRAY_SIZE(gp->funcs))
should be fine.

__match_string() is called on 2 static array of strings in this file. For
this reason, the conversion to the new match_string() macro/helper, was
done in this separate commit.
Using the new match_string() helper is mostly a cosmetic change (at this
point in time). The sizes of the arrays will be computed automatically,
which would only help if they ever get expanded.

The `lcd_types` array is a static array of strings.
Using match_string() (which computes the array size via ARRAY_SIZE())
is possible.
This reduces the array by 1 element, since the NULL (at the end of the
array) is no longer needed.

The change is mostly cosmetic.
The `energy_perf_strings` array is static, so match_string() can be used
(which will implicitly do a ARRAY_SIZE(energy_perf_strings)).
The only small benefit here, is the reduction of the array size by 1

This change re-introduces `match_string()` as a macro that uses
ARRAY_SIZE() to compute the size of the array.
The macro is added in all the places that do
`match_string(_a, ARRAY_SIZE(_a), s)`, since the change is pretty
straightforward.

In-Reply-To: <20190508112842.11654-1-alexandru.ardelean@analog.com>
This change does a rename of match_string() -> __match_string().
There are a few parts to the intention here (with this change):
1. Align with sysfs_match_string()/__sysfs_match_string()
2. This helps to group users of `match_string()` into simple users:
a. those that use ARRAY_SIZE(_a) to specify the number of elements
b. those that use -1 to pass a NULL terminated array of strings
c. special users, which (after eliminating 1 & 2) are not that many
3. The final intent is to fix match_string()/__match_string() which is
slightly broken, in the sense that passing -1 or a positive value does
not make any difference: the iteration will stop at the first NULL
element.

* [PATCH 01/16] lib: fix match_string() helper on -1 array size

In-Reply-To: <20190508112842.11654-1-alexandru.ardelean@analog.com>
The documentation the `_match_string()` helper mentions that `n`
should be:
* @n: number of strings in the array or -1 for NULL terminated arrays
The behavior of the function is different, in the sense that it exits on
the first NULL element in the array, regardless of whether `n` is -1 or a
positive number.
This patch changes the behavior, to exit the loop when a NULL element is
found and n == -1. Essentially, this aligns the behavior with the
doc-string.
There are currently many users of `match_string()`, and so, in order to go
through them, the next patches in the series will focus on doing some
cosmetic changes, which are aimed at grouping the users of
`match_string()`.

* [PATCH 00/16] treewide: fix match_string() helper when array size

Cc: gregkh, andriy.shevchenko, Alexandru Ardelean
The intent of this patch series is to make a case for fixing the
match_string() string helper.
The doc-string of the `__sysfs_match_string()` helper mentions that `n`
(the size of the given array) should be:
* @n: number of strings in the array or -1 for NULL terminated arrays
However, this is not the case.
The helper stops on the first NULL in the array, regardless of whether -1
is provided or not.
There are some advantages to allowing this behavior (NULL elements within
in the array). One example, is to allow reserved registers as NULL in an
array.
One example in the series is patch:
x86/mtrr: use new match_string() helper + add gaps == minor fix
which uses a "?" string for values that are reserved/don't care.
Since the change is a bit big, the change was coupled with renaming
match_string() -> __match_string().
The new match_string() helper (resulted here) does an ARRAY_SIZE() over the
array, which is useful when the array is static.
Also, this way of doing things is a way to go through all the users of this
helpers and check that nothing goes wrong, and notify them about the change
to match_string().
It's a way of grouping changes in a manage-able way.
The first patch is important, the others can be dropped.
