From bbae02035a87a3ef45f751032ec8d2bb6f3ed496 Mon Sep 17 00:00:00 2001 From: Mark Brown Date: Thu, 19 Jun 2008 03:18:09 +0100 Subject: [PATCH] [ARM] 5108/2: PXA SSP: Don't unconditionally free interrupt Callers may stop the SSP core requesting the interrupt so it can't be freed unconditionally. Also use NO_IRQ like we should.
