Subject: ARM: 9240/1: dma-mapping: Pass (void *) to virt_to_page()
X-Git-Tag: v6.6.17~5934^2~34
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=8770b9e575ce5727b4f95b6bcb086247dcce4eb3;p=platform%2Fkernel%2Flinux-rpi.git

ARM: 9240/1: dma-mapping: Pass (void *) to virt_to_page()

Pointers to virtual memory functions are (void *) but the
__dma_update_pte() function is passing an unsigned long.
Fix this up by explicit cast.
