+Subject: [PATCH 4432/4736] drm/amdgpu: remove set but not used variable
+ 'count'
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Fixes gcc '-Wunused-but-set-variable' warning:
+
+drivers/gpu/drm/amd/amdkfd/kfd_device.c: In function
+‘kgd2kfd_post_reset’:
+drivers/gpu/drm/amd/amdkfd/kfd_device.c:745:11: warning:
+variable ‘count’ set but not used [-Wunused-but-set-variable]
+
+'count' is never used, so can be removed. Thus 'atomic_dec_return'
+can be replaced as 'atomic_dec'
+
+Fixes: e42051d2133b ("drm/amdkfd: Implement GPU reset handlers in KFD")
