Subject: [PATCH][next] ASoC: tas2781: Remove redundant initialization of pointer 'data'

The pointer 'data' being initialized with a value that is never read, it
is being re-assigned inside a while-loop. The initialization is redundant
and can be removed.

Cleans up clang scan build warning
sound/soc/codecs/tas2781-fmwlib.c:1534:17: warning: Value stored to
'data' during its initialization is never read [deadcode.DeadStores]
