Subject: [PATCH] drm/amdgpu: remove set but not used variable 'invalid'
Mime-version: 1.0
Content-type: text/plain; charset=UTF-8
Content-transfer-encoding: 8bit
Git-commit: 9e089a29c696d86d26e79737bafbce94738fb462
Patch-mainline: v5.6-rc1
References: bsc#1111666
Fixes gcc '-Wunused-but-set-variable' warning:
Drivers/gpu/drm/amd/amdgpu/amdgpu_amdkfd_gpuvm.c: In function
‘amdgpu_amdkfd_evict_userptr’:
drivers/gpu/drm/amd/amdgpu/amdgpu_amdkfd_gpuvm.c:1665:6: warning:
variable ‘invalid’ set but not used [-Wunused-but-set-variable]
'invalid' is never used, so can be removed. Thus 'atomic_inc_return'
can be replaced as 'atomic_inc'
Fixes: 5ae0283e831a ("drm/amdgpu: Add userptr support for KFD")
