media: vivid: remove redundant assignment to variable checksum
Variable checksum is assigned a value that is never read, it is assigned a new value in a following for-loop. The assignment is redundant and can be removed. Cleans up clang scan build warning: drivers/media/test-drivers/vivid/vivid-vbi-gen.c:197:2: warning: Value stored to 'checksum' is never read [deadcode.DeadStores] Signed-off-by: Colin Ian King <colin.i.king@gmail.com> Signed-off-by: Hans Verkuil <hverkuil-cisco@xs4all.nl>
