Subject: drivers/input: eliminate INPUT_COMPAT_TEST macro
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=b8b4ead11e9d258ccc9a8aea28cc0ac747b044ef;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

drivers/input: eliminate INPUT_COMPAT_TEST macro

INPUT_COMPAT_TEST became much simpler after commit f4056b52845283
("input: redefine INPUT_COMPAT_TEST as in_compat_syscall()") so we can
cleanly eliminate it altogether.
