Subject: [PATCH] drm/amdgpu: remove set but not used variable 'count'
Mime-version: 1.0
Content-type: text/plain; charset=UTF-8
Content-transfer-encoding: 8bit
Git-commit: a1bd079fca6219e18bb0892f0a7228a76dd6292c
Patch-mainline: v5.6-rc1
References: git-fixes
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")
