The compiler is complaining with the following errors:

The expected pointer type of the third argument to dma_alloc_wc() is dma_addr_t but phys_addr_t is passed. Fix this by adding casts to the expected pointer type.

What compiler do you use? I do regular builds and check for warnings and errors, and this one is new to me.
