From 13e87ec68641fd54f3fa04eef3419d034ed2115a Mon Sep 17 00:00:00 2001 From: Andrew Morton Date: Thu, 27 Apr 2006 18:39:18 -0700 Subject: [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.
