Subject: [PATCH] arch/h8300: fix kernel/dma.c build warning
Date: Sat, 21 Jul 2018 03:17:35 +0000	[thread overview]
Message-ID: <b4146df6-93ef-5f4d-9302-2040895d62b0@infradead.org> (raw)

From: Randy Dunlap <rdunlap@infradead.org>

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 *'
