[PATCH][next] spi: rockchip-sfc: Fix assigned but never used return error codes

From: Colin King
Date: Wed Aug 18 2021 - 10:11:03 EST


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

Currently there are two places where the error return variable ret is
being assigned -ETIMEDOUT on timeout errors and this value is not
being returned. Fix this by returning -ETIMEDOUT rather than redundantly
assiging it to ret.

Addresses-Coverity: ("Unused value")
Fixes: 0b89fc0a367e ("spi: rockchip-sfc: add rockchip serial flash controller")
