6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Sakari Ailus <sakari.ailus@xxxxxxxxxxxxxxx>
[ Upstream commit 199c204bcc732ec18dbaec2b9d6445addbd376ea ]
Fix printing DMA and physical address printing on 32-bit platforms, by
using correct types. Also cast DMA_BIT_MASK() result to dma_addr_t to make
Clang happy.
