Subject: drm: omapdrm: fix compiler errors
From: Russell King <rmk+kernel@xxxxxxxxxxxxxxxx>
commit 2d31ca3ad7d5d44c8adc7f253c96ce33f3a2e931 upstream.
Regular randconfig nightly testing has detected problems with omapdrm.
omapdrm fails to build when the kernel is built to support 64-bit DMA
addresses and/or 64-bit physical addresses due to an assumption about
the width of these types.
Use %pad to print DMA addresses, rather than %x or %Zx (which is even
more wrong than %x). Avoid passing a uint32_t pointer into a function
which expects dma_addr_t pointer.
