From: Sascha Hauer Date: Thu, 18 Dec 2008 10:08:55 +0000 (+0100) Subject: [ARM] MXC: remove dependency to other include files from irqs.h X-Git-Tag: v2.6.29-rc1~559^2~8^2~2 X-Git-Url: http://pilppa.com/gitweb/?a=commitdiff_plain;h=9d631b835f518848b7f3ce803bfd00dc1bb8a5b1;p=linux-2.6-omap-h63xx.git [ARM] MXC: remove dependency to other include files from irqs.h This patch removes the inclusion of mach/hardware.h from mach/irqs.h and switches to more meaningful names for the irq related macros.
