This patch removes apparently unnecessary extern declarations in coyote-pci.c and ixdpg425-pci.c within arch/arm/mach-ixp4xx and has been compile-tested without producing warnings or errors. Kernel coding style forbids the use of extern declarations within .c files. Signed-off-by: Michael-Luke Jones <mlj28@cam.ac.uk> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
