If I make format specifier %lld for dma_addr_t then ARM64 compiler is happy, but nios compiler complains
If I make format specifier %d for dma_addr_t then ARM compiler complains, but nios2 is happy
So what is the best way to handle format specifier for dma_addr_t for all architectures?
Regards,
Biju
