[PATCH][next] media: dvb: remove redundant assignment to variable ret

[Colin Ian King]

The variable ret is being assigned a value but it isn't being
read afterwards. The assignment is redundant and so ret can be
removed. Also add spaces after , to clean up checkpatch warnings.

Cleans up clang scan build warning:
warning: Although the value stored to 'ret' is used in the
enclosing expression, the value is never actually read from
'ret' [deadcode.DeadStores]
