Subject: gpio/it8761e: Restrict it8761e gpio driver to x86.
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=265fe02b6fade1704f01c4e96f99ac051b7fab9d;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

gpio/it8761e: Restrict it8761e gpio driver to x86.

This driver does an unconditional read of io space during module init which
causes a bad dereference on ARM.  It looks to me like this is an x86 only
drivers, so restrict it to only compile on x86.
