[PATCH] drm/amdkfd: Add missing #if defined(CONFIG_HSA_AMD_P2P)

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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]
