[PATCH] mtd: spi-nor: cqspi: remove redundant dead code on error return check

From: Colin King
Date: Tue Jan 31 2017 - 10:56:46 EST


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

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
