Subject: Remove unused mutexes
X-Git-Tag: submit/tizen/20220322.224920~3
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=402ef99df651c1d01e2b26c52d0e067aa74cade9;p=platform%2Fkernel%2Flinux-amlogic.git

Remove unused mutexes

Due to changes introduced by the RT patch struct mutex no longer contains
fields that contain self-references. Without them several mutexes appear
as unused and can safely be remove to prevent compilation errors.
