Subject: drm/amdgpu: Fix kcalloc over kzalloc in 'gmc_v9_0_init_mem_ranges'
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=f54e1d47e0204d73c29993deecd81d60bbbfc830;p=linux.git

drm/amdgpu: Fix kcalloc over kzalloc in 'gmc_v9_0_init_mem_ranges'

Replace kzalloc(n * sizeof(...), ...) with kcalloc(n, sizeof(...), ...)
since kcalloc is the preferred API in case of allocating with multiply.

Fixes the below:

WARNING: Prefer kcalloc over kzalloc with multiply
