From: Uwe Kleine-König Date: Tue, 16 Oct 2007 06:03:00 +0000 (+0200) Subject: ns9xxx: Use get_irqnr_preamble to initialize base register X-Git-Tag: v2.6.26-rc1~1131^2~2^8~8 X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=ab65b87093a38ad8565780494c74bd7afd79ad9a;p=linux-2.6 ns9xxx: Use get_irqnr_preamble to initialize base register This patch optimizes the irq handling a bit. Now the base register is only computed once if more than one irq is pending.
