Subject: [PATCH] zram: include linux/err.h
Date: Sat, 15 Mar 2014 10:40:08 +0100	[thread overview]
Message-ID: <201403151040.09139.arnd@arndb.de> (raw)

The zram driver uses the ERR_PTR macro defined in <linux/err.h>
and relies on this header to be included implicitly through
other headers, which is not (always) the case on the ARM architecture.

Adding an explicit #include allows us to build the driver in
all configurations.
