Revision c835a388968f5437491e3fe6e9b0332bc3c52e0e authored by Daniel Ritz on 05 May 2005, 23:15:57 UTC, committed by Linus Torvalds on 05 May 2005, 23:36:43 UTC
Make sure that if the INTRTIE bit is set both functions of the cardbus bridge use the same IRQ before doing any probing... [ yes i hate the TI bridges for the fact that they are very flexible so that so many BIOS vendors get it wrong. ] Signed-off-by: Daniel Ritz <daniel.ritz@gmx.ch> Signed-off-by: Dominik Brodowski <linux@dominikbrodowski.net> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
