From 990e53f880be9ff93072b4cce590ec2826cee0b6 Mon Sep 17 00:00:00 2001 From: Tejun Heo Date: Thu, 2 Aug 2007 21:38:03 +0900 Subject: [PATCH] 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.
