Subject: [PATCH 4/8] drm: Pass pointers to virt_to_page()
Date: Sun, 27 Oct 2013 21:52:39 +0000	[thread overview]
Message-ID: <1382910759.2994.48.camel@deadeye.wl.decadent.org.uk> (raw)
In-Reply-To: <1382910437.2994.43.camel@deadeye.wl.decadent.org.uk>

[-- Attachment #1: Type: text/plain, Size: 2052 bytes --]

Most architectures define virt_to_page() as a macro that casts its
argument such that an argument of type unsigned long will be accepted
without complaint.  However, the proper type is void *, and passing
unsigned long results in a warning on MIPS.

Compile-tested only.

If at first you don't succeed, you're doing about average.
