[PATCH] request_irq(): remove warnings from irq probing
- Add new SA_PROBEIRQ which suppresses the new sharing-mismatch warning. Some drivers like to use request_irq() to find an unused interrupt slot. - Use it in i82365.c - Kill unused SA_PROBE. Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
