2015-11-03net/mlx5e: Avoid NULL pointer access in case of configuration failureAchiad Shochat
In case a configuration operation that involves closing and re-opening resources (e.g RX/TX queue size change) fails at the re-opening stage these resources will remain closed. So when executing (following) configuration operations (e.g ifconfig down) we cannot assume that these resources are available.

2015-11-03s390/dasd: fix disconnected device with valid path maskStefan Haberland
Path verification is either done via dasd_eckd_read_conf() which is triggered during online processing and resume or via do_path_verification_work() which is triggered after path events. The dasd_eckd_read_conf() version added paths unconditionally and did not check if the path mask was empty. This led to devices having the disconnected stop flag set but a valid path mask. So they where not working although they had paths validated successfully. After a resume this state could even not be solved with additional paths added. Fix by checking for an empty path mask in dasd_eckd_read_conf() and clearing the device stop bits for a newly added channel path.

2015-11-03s390/dasd: fix invalid PAV assignment after suspend/resumeStefan Haberland
For a valid PAV assignment the DASD driver needs to notice possibly changed configuration data. Thus the failing of read configuration data should also fail the device restore to prevent invalid PAV assignment. The failed device may get restored after additional paths get available later on. If the restore fails after the device was added to the lcu alias handling it needs to be removed from the alias handling before exiting the restore function.

2015-11-03s390/dasd: fix double free in dasd_eckd_read_confStefan Haberland
The configuration data is stored per path and also the first valid configuration data per device. When dasd_eckd_read_conf is called again after a path got lost the device configuration data is cleared but possibly not the per path configuration data. This might lead to a double free when the lost path gets operational again. Fix by clearing all per path configuration data when the first valid configuration data is received and stored.

The pad handling code introduced for the Cintiq Companion 2 (f7acb55) looks at the wrong bytes in the report when deciding whether ABS_MISC should be sent. This does not cause any issues with the X driver now that the pen and pad have been split to separate devices, but is incorrect and has caused issues when backporting to distros with pre- 3.17 kernels.

When support for the Cintiq Companion Hybrid and Cintiq Companion 2 was added (36d3c51 and f7acb55), the 'wacom_query_tablet_data' function was updated to include references to CINTIQ_HYBRID and CINTIQ_COMPANION_2 with the thought that they were necessary to switch the touch interface into the proper mode. This is unnecessary, however, since those types are only ever associated with the pen interface -- the touch interfaces are either CINTIQ_24HDT or HID_GENERIC. To avoid confusion in the future, we remove the unnecessary CINTIQ_HYBRID and CINTIQ_COMPANION_2 conditions.
