Subject[PATCH] usb: musb: Fix format specifier warning
Date
This patch fixes a format specifier warning. dma_addr_t can be either
u32 or u64 so we should cast to the largest type and change the format
specifier to %llx.
The addition of urb->transfer_dma and urb->actual_length is also done a
few lines below. I have moved this code up and pass the variable buf to
dev_dbg.

Sparse output:
drivers/usb/musb/musb_host.c:1761:4: warning:
format ‘%x’ expects argument of type ‘unsigned int’,
but argument 6 has type ‘dma_addr_t’ [-Wformat]
