[PATCH] 3c59x PM fixes
This patch adds some missing pci-related calls to the suspend and resume routines of the 3c59x driver. It also makes the driver free/request IRQ on suspend/resume, in accordance with the proposal at: http://lists.osdl.org/pipermail/linux-pm/2005-May/000955.html Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
