Subject: backlight: lm3630a_bl: Remove redundant 'flush_workqueue()' calls
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=adc122011125682932ef279d717153670feedde4;p=linux.git

backlight: lm3630a_bl: Remove redundant 'flush_workqueue()' calls

'destroy_workqueue()' already drains the queue before destroying it, so
there is no need to flush it explicitly.

Remove the redundant 'flush_workqueue()' calls.
