Subject: [PATCH][next] ASoC: codecs: rt298: remove redundant assignment to d_len_code

Variable d_len_code is being initialized to zero and then re-assigned a
different value in all the valid cases in the following switch statement.
The only place it is not being assigned a value is on the return for
a default case and in this case it does not need to be assigned. The
initialization is redundant and can be removed.
