When the sun4i DRM driver is compiled with LPAE enabled, dma_addr_t turns
into a 64-bit type, which causes warnings with some debug printks:
=================
In file included from
drivers/gpu/drm/sun4i/sun4i_backend.c:13::
drivers/gpu/drm/sun4i/sun4i_backend.c: In function
'sun4i_backend_update_layer_buffer':
drivers/gpu/drm/sun4i/sun4i_backend.c:193:19: warning:
format '%x' expects argument of type 'unsigned int', but argument 3 has
type 'dma_addr_t {aka long long unsigned int}' [-Wformat=]
DRM_DEBUG_DRIVER("Using GEM @ 0x%x\n", gem->paddr);
^
include/drm/drmP.h:207:34: note: in definition of macro
'DRM_DEBUG_DRIVER'
drm_ut_debug_printk(__func__, fmt, ##args); \
.....
Use the proper printk format specifier [1] for dma_addr_t which takes
care of those differences.
