Subject: sysfs: make sysfs_addrm_finish() return void
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=990e53f880be9ff93072b4cce590ec2826cee0b6;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

sysfs: make sysfs_addrm_finish() return void

With the previous sysfs_add_one() update, there is only one user of
the return value of sysfs_addrm_finish() and the user can switch to
testing @sd easily.  Make sysfs_addrm_finish() return void for cleaner
semantics as suggested by Satyam Sharma.

This patch doesn't introduce any noticeable behavior change.
