The variable 'i' in function kfd_dev_create_p2p_links is only used in codes that gaurded by '#if defined(CONFIG_HSA_AMD_P2P)' check. So adding CONFIG_HSA_AMD_P2P #ifdef check around variable 'i' too.
Fixes the following w1 warning: drivers/gpu/drm/amd/amdgpu/../amdkfd/kfd_topology.c:1542:11: warning: variable 'i' set but not used [-Wunused-but-set-variable] Reported-by: kernel test robot <[email protected]> Signed-off-by: sunliming <[email protected]> --- drivers/gpu/drm/amd/amdkfd/kfd_topology.c | 6 ++++-- 1 file changed, 4 insertions(+), 2 deletions(-) diff --git a/drivers/gpu/drm/amd/amdkfd/kfd_topology.c b/drivers/gpu/drm/amd/amdkfd/kfd_topology.c index 304322ac39e6..4bfce71f7fa9 100644 --- a/drivers/gpu/drm/amd/amdkfd/kfd_topology.c +++ b/drivers/gpu/drm/amd/amdkfd/kfd_topology.c @@ -1539,7 +1539,10 @@ static int kfd_dev_create_p2p_links(void) { struct kfd_topology_device *dev; struct kfd_topology_device *new_dev; - uint32_t i, k; + uint32_t k; +#if defined(CONFIG_HSA_AMD_P2P) + uint32_t i = 0; +#endif int ret = 0; k = 0; @@ -1553,7 +1556,6 @@ static int kfd_dev_create_p2p_links(void) return 0; k--; - i = 0; /* create in-direct links */ ret = kfd_create_indirect_link_prop(new_dev, k); -- 2.25.1
