[PATCH 06/10] drivers/input/serio/i8042: Use pr_<level>, pr_fmt. Fix dbg and __FILE__ use

[Joe Perches]

Standardized message logging prefixes.
Removed \n from dbg macro, added \n to each dbg call site.
A couple of uses of dbg already had a \n.
Removed direct use of __FILE__ from dbg, converted to pr_fmt(fmt)
Added non-debug printf argument verification of dbg calls
Removed "i8042.c" from printks, converted to pr_<level>

Did you test it? It looks for call like:

> +                 data, str & I8042_STR_AUXDATA ? "aux" : "kbd");

the result will be:

printk(KERN_DEBUG "i8042: %02x <- i8042 (flush, %s)\n [%d]", ...)

which is not exactly what you want...

Not quite equivalent conversion, right now every port is registered with
message "serio: XXX at YYY". I would be OK with having driver prefix
going in front but I'd like to keep word serio in (like "i8042: serio
XXX at YYY").

Thanks.

Right.  My mistake.
I compile tested only and didn't notice the badly formed string.

Mind if I move the time to the front like this?

+#define dbg(format, arg...)                                            \

I'll resubmit a pr_<level> series for drivers/input/serio

Another option would be to leave '\n' in dbg() and leave most of the
callers as is.

That's really error prone though.

$ grep -w dbg drivers/input/serio/i8042.c | cat -n
     1			dbg("%02x <- i8042 (flush, %s)", data,
     2		dbg("%02x -> i8042 (command)", command & 0xff);
     3			dbg("%02x -> i8042 (parameter)", param[i]);

    10			if (irq) dbg("Interrupt %d, without any data", irq);

    14			dbg("     -- i8042 (aux irq test timeout)");
    15		dbg("%02x -> i8042 (panic blink)", 0xed);
    16		dbg("%02x -> i8042 (panic blink)", led);

I think 2 defects in 16 uses is a pretty high error rate.

But how not adding /n is it much better than having it if some later change will forget to add it to the message?

Adding \n is the default kernel style.

USB uses a similar dbg macro with a relatively
high error rate.

I fixed some in this commit below awhile ago,
but these keep creeping back in, so they _are_
error prone in actual use.

commit 759f3634267a67ac90f3fa7fc06510dfd43b4e45

Date:   Fri Feb 5 16:50:08 2010 -0800

    USB: serial: Remove unnecessary \n's from dbg uses
    
    #define dbg adds the newline, messages shouldn't.
    Converted dbg("%s", "some string") to dbg("some string")
