X-Git-Tag: v5.10.7~2421^2~8 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=f187b6974f6dfbeba4aafda972cc37f27d091b73;p=platform%2Fkernel%2Flinux-rpi.git workqueue: Use IS_ERR and PTR_ERR instead of PTR_ERR_OR_ZERO. Replace inline function PTR_ERR_OR_ZERO with IS_ERR and PTR_ERR to remove redundant parameter definitions and checks. Reduce code size.
