From: Paul Walmsley Date: Tue, 22 Jul 2008 23:51:45 +0000 (-0600) Subject: TWL4030: use symbolic ISR/IMR register names during twl_init_irq() X-Git-Tag: v2.6.26-omap1~56 X-Git-Url: http://pilppa.com/gitweb/?a=commitdiff_plain;h=5717598f19a100da89b136798af2cb8075c66063;p=linux-2.6-omap-h63xx.git TWL4030: use symbolic ISR/IMR register names during twl_init_irq() twl_init_irq() uses a bunch of magic numbers as register indices; this has already led to several errors, fixed earlier in this patch series. Now use descriptive macros instead of magic numbers. This patch should not change kernel behavior.
