From: Arnd Bergmann <arnd@xxxxxxxx>
gcc points out an invalid bit shift operation on 32-bit architectures
with 64-bit dma_addr_t:
drivers/gpu/drm/tegra/hub.c: In function 'tegra_shared_plane_atomic_update':
include/vdso/bits.h:7:40: error: left shift count >= width of type [-Werror=shift-count-overflow]
7 | #define BIT(nr) (UL(1) << (nr))
| ^~
drivers/gpu/drm/tegra/hub.c:513:25: note: in expansion of macro 'BIT'
513 | base |= BIT(39);
| ^~~
Use the correct BIT_ULL() macro to always generate a 64-bit mask.
Fixes: 7b6f846785f4 ("drm/tegra: Support sector layout on Tegra194")
