Subject: r8152: check WORK_ENABLE in suspend function
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=e3bd1a81cd1e3f8ed961e642e97206d715db06c4;p=linux-beck.git

r8152: check WORK_ENABLE in suspend function

Avoid unnecessary behavior when autosuspend occurs during open().
The relative processes should only be run after finishing open().
