From: Ezequiel Garcia Date: Mon, 18 Jun 2018 04:38:51 +0000 (-0400) Subject: media: s5p-g2d: Remove unrequired wait in .job_abort X-Git-Tag: v5.15~8227^2~245 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=774f1c912776330ece84540fac370ec201c878b4;p=platform%2Fkernel%2Flinux-starfive.git media: s5p-g2d: Remove unrequired wait in .job_abort As per the documentation, job_abort is not required to wait until the current job finishes. It is redundant to do so, as the core will perform the wait operation. Remove the wait infrastructure completely.
