drm/amdgpu/powerplay/smu7: fix unintialized data usage
A recent bugfix replaced an out-of-bounds access with direct
use of unintialized data:
drivers/gpu/drm/amd/powerplay/hwmgr/smu7_hwmgr.c: In function 'smu7_patch_limits_vddc':
drivers/gpu/drm/amd/powerplay/hwmgr/smu7_hwmgr.c:2033:6: error: 'vddc' may be used uninitialized in this function [-Werror=maybe-uninitialized]
drivers/gpu/drm/amd/powerplay/hwmgr/smu7_hwmgr.c:2146:11: note: 'vddc' was declared here
drivers/gpu/drm/amd/powerplay/hwmgr/smu7_hwmgr.c:2033:6: error: 'vddci' may be used uninitialized in this function [-Werror=maybe-uninitialized]
drivers/gpu/drm/amd/powerplay/hwmgr/smu7_hwmgr.c:2146:17: note: 'vddci' was declared here
uint32_t vddc, vddci;
This initializes the data as before using the correct type.
