[PATCH] crypto: caam/qi2: remove redundant assignment to ret

From: Colin King
Date: Thu Jun 11 2020 - 11:39:42 EST


From: Colin Ian King <colin.king@xxxxxxxxxxxxx>

The variable ret is being assigned a value that is never read, the
error exit path via label 'unmap' returns -ENOMEM anyhow, so assigning
ret with -ENOMEM is redundamt.

Addresses-Coverity: ("Unused value")
