Subject[PATCH] mtd: spi-nor: cqspi: remove redundant dead code on error return check
Date
From: Colin Ian King <colin.king@canonical.com>

Checking for ret < 0 is redundant because a previous check on ret
being non-zero already handles the ret < 0 case. Remove the redundant
code. Found by CoverityScan, CID#1398863, CID#1398864
