drm/vmwgfx: use *_32_bits() macros
commit 0e7c875d1ae9dcf4d8c6018a45e5529feaef8956 upstream.
Use the upper_32_bits() macro instead of the four line equivalent that
triggers a GCC warning on 32 bits x86:
drivers/gpu/drm/vmwgfx/vmwgfx_cmdbuf.c: In function 'vmw_cmdbuf_header_submit':
drivers/gpu/drm/vmwgfx/vmwgfx_cmdbuf.c:297:25: warning: right shift count >= width of type [-Wshift-count-overflow]
val = (header->handle >> 32);
^
And use the lower_32_bits() macro instead of and-ing with a 32 bits
mask.
