Subject: [PATCH] drm/msm/gem: Fix double resv lock aquire
Date: Tue, 30 Jan 2024 14:35:33 -0800
Message-ID: <20240130223533.25713-1-robdclark@gmail.com>

From: Rob Clark <robdclark@chromium.org>

Since commit 56e5abba8c3e ("dma-buf: Add unlocked variant of vmapping
functions"), the resv lock is already held in the prime vmap path, so
don't try to grab it again.

Fixes: 56e5abba8c3e ("dma-buf: Add unlocked variant of vmapping functions")
