Subject: workqueue: trivial fix for return statement in work_busy()
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=999767beb1b4a10eabf90e6017e496536cf4db0b;p=linux-beck.git

workqueue: trivial fix for return statement in work_busy()

Return type of work_busy() is unsigned int.
There is return statement returning boolean value, 'false' in work_busy().
It is not problem, because 'false' may be treated '0'.
However, fixing it would make code robust.
