When SWIOTLB is configured, if without this patch kernel compilation
fails with such error messages:
drivers/gpu/drm/radeon/radeon_ttm.c: In function 'radeon_ttm_tt_populate':
drivers/gpu/drm/radeon/radeon_ttm.c:606:2: error: implicit declaration of
function 'swiotlb_nr_tbl'
drivers/gpu/drm/radeon/radeon_ttm.c:607:3: warning: passing argument 2 of
'ttm_dma_populate' from incompatible pointer type
include/drm/ttm/ttm_page_alloc.h:81:12: note: expected 'struct device *' but
argument is of type 'struct device *'
drivers/gpu/drm/radeon/radeon_ttm.c: In function 'radeon_ttm_tt_unpopulate':
drivers/gpu/drm/radeon/radeon_ttm.c:653:3: warning: passing argument 2 of
'ttm_dma_unpopulate' from incompatible pointer type
include/drm/ttm/ttm_page_alloc.h:82:13: note: expected 'struct device *' but
argument is of type 'struct device *'
V2:
1, Add compilation error messages;
2, Make the From: address the same as Signed-off-by address.
