Subject: [PATCH 25/75] sysfs: make sysfs_addrm_finish() return void

From: Tejun Heo <htejun@...il.com>

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.
