From 9b7e31bbf4bb58b12e11a7f24b7c3e48bbd2f4da Mon Sep 17 00:00:00 2001 From: Lars-Peter Clausen Date: Wed, 4 Jul 2012 13:02:56 -0700 Subject: Input: request threaded-only IRQs with IRQF_ONESHOT Since commit 1c6c69525b ("genirq: Reject bogus threaded irq requests") threaded IRQs without a primary handler need to be requested with IRQF_ONESHOT, otherwise the request will fail. This patch adds the IRQF_ONESHOT to input drivers where it is missing. Not modified by this patch are those drivers where the requested IRQ will always be a nested IRQ (e.g. because it's part of an MFD), since for this special case IRQF_ONESHOT is not required to be specified when requesting the IRQ.
