Hey Emil.
I believe you can not use %pa with a dma_addr_t
because that could be a different size than a
phy_addr_t.
(the vsprintf cast and deref is to a phy_addr_t)
The definitions are: (types.h)
#ifdef CONFIG_ARCH_DMA_ADDR_T_64BIT
typedef u64 dma_addr_t;
#else
typedef u32 dma_addr_t;
#endif /* dma_addr_t */
[]
#ifdef CONFIG_PHYS_ADDR_T_64BIT
typedef u64 phys_addr_t;
#else
typedef u32 phys_addr_t;
#endif
