there is an else here too!
With the patch the checkpatch warns:
CHECK: braces {} should be used on all arms of this statement
#201: FILE: drivers/dma/imx-sdma.c:2161:
+ if (ret)
[...]
+ else {
[...]
Even if the if is a single block and else being multi block, if would
need matching brances. With the change pushed:
total: 0 errors, 0 warnings, 0 checks, 60 lines checked
