From 50658b6602dad6dc76c226917f5d8cec0f680eab Mon Sep 17 00:00:00 2001 From: Linus Walleij Date: Tue, 2 Aug 2011 11:29:24 +0200 Subject: [PATCH] spi/pl022: remove function cannot exit The remove function in the PL022 driver cannot abort the remove function any way, so restructure the code so as not to make that assumption. Remove will now proceed no matter whether it can stop the transfer queue or not.
