[PATCH 00/22] Random ARM randconfig fixes in drivers

[Arnd Bergmann]

These are a bunch of fixes I had to do to get all randconfig
configurations on ARM working. Most of these are really old
bugs, but there are also some new ones. I don't think any of
them require a backport to linux-stable.

I have checked that they are all still required on yesterday's
linux-next kernel. Please apply on the appropriate trees unless
there are objections.

Patch numbers are per subsystem, which I thought is less confusing
than numbering them 1-22 when they are all totall independent.

[PATCH 1/2] input: fix ps2/serio module dependency

[Arnd Bergmann]

The ps2 mouse and keyboard drivers use the "serio" framework that
they correctly select in Kconfig, and that in turn depends on the
i8042 driver, which is also allowed to be disabled for architectures
that don't have an i8042.

However, Kconfig also allows i8042 to be built as a module while
the serio framework is built-in, which causes this link error:

drivers/built-in.o: In function `ps2_begin_command':
:(.text+0x26b6cc): undefined reference to `i8042_check_port_owner'
:(.text+0x26b6d4): undefined reference to `i8042_lock_chip'
drivers/built-in.o: In function `ps2_end_command':
:(.text+0x26b734): undefined reference to `i8042_check_port_owner'
:(.text+0x26b73c): undefined reference to `i8042_unlock_chip'

On x86, a specific 'select SERIO_I8042' takes care of it, but
not on the other architecture that potentially have a u8042.

This patch changes the Kconfig logic to ensure that whenever
there is an i8042, it does get used for the serio driver, avoiding
the link error above.

x86 also selects ARCH_MIGHT_HAVE_PC_SERIO so shouldn't this be

	select SERIO_I8042 if ARCH_MIGHT_HAVE_PC_SERIO

?

I can fix it up on my side if you agree.

Thanks.

Yes, sounds good, thanks!

[PATCH 2/2] input: atmel-wm97xx: only build for AVR32

[Arnd Bergmann]

Building this driver on ARM/at91 always gives us this error message:

drivers/input/touchscreen/atmel-wm97xx.c:63:2: error: #error Unknown CPU, this driver only supports AT32AP700X CPUs.

Clearly this configuration is not meant to work, so let's just prevent
it in Kconfig. If we ever want to use it on another platform, we should
also pass proper resources for GPIO, IRQ and memory, which are hardcoded
to AT32AP700X at the moment.

Is this series of patches also going to fix arm:allmodconfig ?

Possibly, I haven't checked in a while. I'm unfortunately sitting on
about 200 other patches in the same branch, which together fix all
build errors in any configuration I encountered.

I should really do some allmodconfig/allnoconfig/allyesconfig
builds without my series again, and prioritize sending out the
ones required for that.
