mei: revamp io list cleanup function.

2017-01-31T10:07:43Z

Specify in function names by which object is the io list filtered: cl for a client and fp for file descriptor. In that course a code duplication is resolved by dropping mei_cl_read_cb_flush and mei_clear_list and using mei_io_list_free_fp function.

mei: replace callback structures used as list head by list_head

2017-01-31T10:07:43Z

mei_dev structure used struct mei_cl_cb type variables as for holding callbacks list heads. Replace them by the actual struct list_head as there is no other info that is handled. This slims down the mei_dev structure and mostly streamline the code. Signed-off-by: Alexander Usyskin Signed-off-by: Tomas Winkler Signed-off-by: Greg Kroah-Hartman

mei: amthif: clean command queue upon disconnection

2017-01-31T10:07:43Z

In order to prevent memory leak clean up the amthif command queue upon disconnection. The issue may happen only on error path as the command queue is cleaned upon file descriptor close. And remove the cleanup from mei_cl_flush_queues as this code is never reached for amthif client. Signed-off-by: Tomas Winkler Signed-off-by: Alexander Usyskin Signed-off-by: Greg Kroah-Hartman

mei: abort waiting for notification on unsupported HW

2017-01-31T10:07:43Z

mei: return error on notification request to a disconnected client

2017-01-31T10:07:43Z

mei: bus: prevent hardware module unload if device on bus is active

2017-01-31T10:07:43Z

The hardware module should not be unloaded if the bus has active devices.

mei: move write cb to completion on credentials failures

2017-01-04T17:22:44Z

The credentials handling was pushed to the write handlers but error handling wasn't done properly. Move write callbacks to completion queue to destroy them and to notify a blocked writer about the failure Fixes: 136698e535cd1 (mei: push credentials inside the irq write handler) Signed-off-by: Alexander Usyskin Signed-off-by: Tomas Winkler Signed-off-by: Greg Kroah-Hartman
