This patch fixes up compiling of the gtwx5715 board setup code, which has apparently been broken since 2.6.18 and the generic IRQ changes. In addition it removes some unecessary extern declarations in the gtwx5715-pci.c file. Signed-off-by: Michael-Luke Jones <mlj28@cam.ac.uk> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
