Subject: [PATCH][next] iio: adc: ti-ads7950: remove redundant assignment to variable ret

Variable ret is being assigned a value that is never read, the variable
is being re-assigned again a few statements later. Remove it.

Cleans up clang scan build warning:
warning: Value stored to 'ret' is never read [deadcode.DeadStores]
