From 87421cb6010a2f6494938fbe0a95e1b096b3b7af Mon Sep 17 00:00:00 2001 From: Solomon Peachy Date: Mon, 23 Sep 2013 16:00:04 -0400 Subject: [PATCH] cw1200: Use a threaded oneshot irq handler for cw1200_spi This supercedes the older patch ("cw1200: Don't perform SPI transfers in interrupt context") that badly attempted to fix this problem. This is a far simpler solution, which has the added benefit of actually working. Signed-off-by: Solomon Peachy Signed-off-by: John W.
