The new driver uses a phys_addr_t to store a DMA address,
which does not work when the two are different size:
drivers/hid/amd-sfh-hid/amd_sfh_client.c:157:11: error: incompatible pointer types passing 'phys_addr_t *' (aka 'unsigned int *') to parameter of type 'dma_addr_t *' (aka 'unsigned long long *') [-Werror,-Wincompatible-pointer-types]
&cl_data->sensor_phys_addr[i],
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~
include/linux/dma-mapping.h:393:15: note: passing argument to parameter 'dma_handle' here
dma_addr_t *dma_handle, gfp_t gfp)
^
Change both the type and the variable name to dma_addr for consistency.
