2016-04-15mwifiex: factor out mwifiex_cancel_pending_scan_cmdAndreas Fenkart4-53/+27
Releasing the scan_pending lock in mwifiex_check_next_scan_command introduces a short window where pending scan commands can be removed or added before removing them all in mwifiex_cancel_pending_scan_cmd. I think this is safe, since the worst thing to happen is that a pending scan cmd is removed by the command handler. Adding new scan commands is not possible while one is pending, see scan_processing flag. Since all commands are removed from the queue anyway, we don't care if some commands are removed by a different code path earlier, the final state remains the same. I assume, that the critical section needed for the check has been extended over clearing the pending scan queue out of convenience. The lock was already held and releasing it and grab it again was just more work. It doesn't seem to be necessary because of concurrency.

2016-04-15devcoredump: add scatterlist supportAviya Erenfeld1-2/+2
Add scatterlist support (dev_coredumpsg) to allow drivers to avoid vmalloc() like dev_coredumpm(), while also avoiding the module reference that the latter function requires. This internally uses dev_coredumpm() with function inside the devcoredump module, requiring removing the const (which touches the driver using it.)

2016-04-14mwifiex: do not wait on semaphore during card removalXinming Hu1-1/+1
Host hang is observed if card is removed before firmware download gets completed. In this case, firmware will be failed to download and adapter structure gets freed. In other thread, mwifiex_remove_card() waits on semaphore until the firmware download fails. This wait is not necessary and may result in invalid adapter access.
