X-Git-Tag: v5.10.7~3385^2~1
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=050d2a8b6992fd012773e75de9f82d45e3b3dfff;p=platform%2Fkernel%2Flinux-rpi.git

cifs: use PTR_ERR_OR_ZERO() to simplify code

PTR_ERR_OR_ZERO contains if(IS_ERR(...)) + PTR_ERR, just use
PTR_ERR_OR_ZERO directly.
