From 6dcfca78d4c036c9d012f913e2a622aae218827f Mon Sep 17 00:00:00 2001 From: Stefan Bader Date: Thu, 27 Apr 2006 18:40:04 -0700 Subject: [PATCH] s390: enable interrupts on error path Interrupts can stay disabled if an error occurred in _chp_add(). Use spin_unlock_irq on the error paths to reenable interrupts.
