From 329fddd7b60cf6aed53cdb6fdc8e64117b8e8bc6 Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Thu, 2 Jan 2014 13:07:37 +0100 Subject: [PATCH] cris: sync_serial: remove interruptible_sleep_on sleep_on and its variants are racy and going away. This replaces the two uses in the cris sync_serial drivers with the equivalent but race-free wait_event_interruptible.
