Subject: [PATCH] video: remove set but not used variable 'ulScaleRight'
Date: Sun, 19 Jan 2020 20:19:45 +0800 [thread overview]
Message-ID: <20200119121945.12517-1-yukuai3@huawei.com> (raw)
Fixes gcc '-Wunused-but-set-variable' warning:
drivers/video/fbdev/kyro/STG4000OverlayDevice.c: In function
‘SetOverlayViewPort’:
drivers/video/fbdev/kyro/STG4000OverlayDevice.c:334:19: warning:
variable ‘ulScaleRight’ set but not used [-Wunused-but-set-variable]
It is never used, and so can be removed.
