Subject: drm/msm: Use dma_resv locking wrappers
Git-commit: 80f30930b6e9bfcb264e8b2e82b05abf3e1a8727
Patch-mainline: v5.6-rc1
References: jsc#SLE-12680, jsc#SLE-12880, jsc#SLE-12882, jsc#SLE-12883, jsc#SLE-13496, jsc#SLE-15322
I'll add more fancy logic to them soon, so everyone really has to use
them. Plus they already provide some nice additional debug
infrastructure on top of direct ww_mutex usage for the fences tracked
by dma_resv.
