When compiling with gcc version 14.0.0 20231220 (experimental)
and W=1, I've noticed the following warning:
drivers/gpu/drm/nouveau/nouveau_svm.c: In function
'nouveau_svm_fault_buffer_ctor':
drivers/gpu/drm/nouveau/nouveau_svm.c:1014:40: warning: 'kvcalloc' sizes
specified with
'sizeof' in the earlier argument and not in the later argument
[-Wcalloc-transposed-args]
1014 | buffer->fault = kvcalloc(sizeof(*buffer->fault),
buffer->entries, GFP_KERNEL);
| ^
Since 'n' and 'size' arguments of 'kvcalloc()' are multiplied to
calculate the final size, their actual order doesn't affect the
result and so this is not a bug. But it's still worth to fix it.
