The STi drm driver correctly warns about invalid format strings when built with 64-bit dma_addr_t: sti_hqvdp.c: In function 'sti_hqvdp_vtg_cb': sti_hqvdp.c:605:119: warning: format '%x' expects argument of type 'unsigned int', but argument 5 has type 'dma_addr_t {aka long long unsigned int}' [-Wformat=] sti_hqvdp.c: In function 'sti_hqvdp_atomic_update': sti_hqvdp.c:931:118: warning: format '%x' expects argument of type 'unsigned int', but argument 5 has type 'dma_addr_t {aka long long unsigned int}' [-Wformat=] This could be changed to using the %pad format string, but that does not work when printing an rvalue, so instead I'm changing the type in the sti_hqvdp structure to u32, which is what gets written into the registers anyway.
