Subject: [PATCH v2] arm: vt8500: Fix build warning in uncompress.h [for 3.7]
Date: Mon,  8 Oct 2012 09:56:45 +1300	[thread overview]
Message-ID: <1349643405-27943-1-git-send-email-linux@prisktech.co.nz> (raw)

This removes a build-time warning in uncompress.h due to incorrectly
cast values being passed to readb/writeb.

Removed arm/io.h and readb/writeb. Read/write directly to the serial
port with a volatile pointer.
