nouveau/svm: fix kvcalloc() argument order
[ Upstream commit 2c80a2b715df75881359d07dbaacff8ad411f40e ]
The conversion to kvcalloc() mixed up the object size and count
arguments, causing a warning:
drivers/gpu/drm/nouveau/nouveau_svm.c: In function 'nouveau_svm_fault_buffer_ctor':
drivers/gpu/drm/nouveau/nouveau_svm.c:1010:40: error: 'kvcalloc' sizes specified with 'sizeof' in the earlier argument and not in the later argument [-Werror=calloc-transposed-args]
1010 | buffer->fault = kvcalloc(sizeof(*buffer->fault), buffer->entries, GFP_KERNEL);
| ^
drivers/gpu/drm/nouveau/nouveau_svm.c:1010:40: note: earlier argument should specify number of elements, later size of each element
The behavior is still correct aside from the warning, but fixing it avoids
the warnings and can help the compiler track the individual objects better.
