drm/meson: Fix overflow implicit truncation warnings
Fix -Woverflow warnings for drm/meson driver which is a result
of moving arm64 custom MMIO accessor macros to asm-generic function
implementations giving a bonus type-checking now and uncovering these
overflow warnings.
drivers/gpu/drm/meson/meson_viu.c: In function ‘meson_viu_init’:
drivers/gpu/drm/meson/meson_registers.h:1826:48: error: large integer implicitly truncated to unsigned type [-Werror=overflow]
#define VIU_OSD_BLEND_REORDER(dest, src) ((src) << (dest * 4))
^
drivers/gpu/drm/meson/meson_viu.c:472:18: note: in expansion of macro ‘VIU_OSD_BLEND_REORDER’
