Subject: Input: soc_button_array - fix a crash during rmmod
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=7740fc52105c9e6d2beac389a9ae0ce7138cf5ab;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

Input: soc_button_array - fix a crash during rmmod

When the system has zero or one button available, trying to rmmod
soc_button_array will cause crash. Fix this by properly handling -ENODEV
in probe().
