From 310df69c26f93c49bb176e95e4eb42ece58a5fd2 Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Thu, 2 Jan 2014 13:07:35 +0100 Subject: [PATCH] staging: panel: fix interruptible_sleep_on race interruptible_sleep_on is racy and going away. This replaces the one caller in the panel driver with the appropriate wait_event_interruptible variant.
