[ Upstream commit 200f351e27f014fcbf69b544b0b4b72aeaf45fd3 ]
Fix build warning in arch/hexagon/kernel/dma.c by casting a void *
to unsigned long to match the function parameter type.
../arch/hexagon/kernel/dma.c: In function 'arch_dma_alloc':
../arch/hexagon/kernel/dma.c:51:5: warning: passing argument 2 of 'gen_pool_add' makes integer from pointer without a cast [enabled by default]
../include/linux/genalloc.h:112:19: note: expected 'long unsigned int' but argument is of type 'void *'
