From: Peter Hüwe on 29 Jun 2010 13:40 From: Peter Huewe <peterhuewe(a)gmx.de> This patch fixes a build failure [1-4] in the atmel_serial code introduced by patch the patch ARM: 6092/1: atmel_serial: support for RS485 communications (e8faff7330a3501eafc9bfe5f4f15af444be29f5) The build failure was caused by missing struct field and missing defines for the avr32 board - the patch fixes this.
