3.18-stable review patch. If anyone has any objections, please let me know. ------------------ From: Sebastian Ott <sebott@xxxxxxxxxxxxxxxxxx> [ Upstream commit 410d5e13e7638bc146321671e223d56495fbf3c7 ] When we terminate driver I/O (because we need to stop using a certain channel path) we also need to ensure that a timer (which may have been set up using ccw_device_start_timeout) is cleared.
