From 52c28d4b0a0849f608c1623f97d936a0d7ffbfea Mon Sep 17 00:00:00 2001 From: Jeff Garzik Date: Fri, 26 Oct 2007 09:00:37 -0300 Subject: [PATCH] V4L/DVB (6407): planb: fix obvious interrupt handling bugs irq handlers have returned a return value for years now... catch up with the times. Also, ditch unneeded prototype.
