[PATCH] gpu: host1x: Fix compiler errors

From: Emil Goode
Date: Mon Mar 26 2018 - 10:44:45 EST


The compiler is complaining with the following errors:

drivers/gpu/host1x/cdma.c:94:48: error:
passing argument 3 of âdma_alloc_wcâ from incompatible pointer type
[-Werror=incompatible-pointer-types]

drivers/gpu/host1x/cdma.c:113:48: error:
passing argument 3 of âdma_alloc_wcâ from incompatible pointer type
[-Werror=incompatible-pointer-types]

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.
