From mboxrd@z Thu Jan 1 00:00:00 1970 From: linux@prisktech.co.nz (Tony Prisk) Date: Mon, 8 Oct 2012 09:56:45 +1300 Subject: [PATCH v2] arm: vt8500: Fix build warning in uncompress.h [for 3.7] Message-ID: <1349643405-27943-1-git-send-email-linux@prisktech.co.nz> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org 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.
