mwifiex: mwifiex_unmap_pci_memory() handling for sleep confirm
Sleep confirm is a special command for which "adapter->cur_cmd" pointer is not set. When it's response is received, host writes SLEEP confirm done to a register. Firmware will perform DMA for writing sleep cookie signature on same buffer after this. Let's not immediately call mwifiex_unmap_pci_memory() for this special command. Unmapping will be done when firmware completes writing sleep cookie signature. Signed-off-by: Amitkumar Karwar <akarwar@marvell.com> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>

lock `pl330->lock', whereas in the rest of the code `pch->work_list' is protected by `pch->lock'. I don't know if this may cause race conditions. Similarly `pch->cyclic' is written by `pl330_alloc_chan_resources' under `pl330->lock' but read by `pl330_tx_submit' under `pch->lock'. Second, I have removed locking from `pl330_request_channel' and `pl330_release_channel' functions. Function `pl330_request_channel' is only called from `pl330_alloc_chan_resources', so the lock is already held. Function `pl330_release_channel' is called from `pl330_free_chan_resources', which already holds the lock, and from `pl330_del'. Function `pl330_del' is called in an error path of `pl330_probe' and at the end of `pl330_remove', but I assume that there cannot be concurrent accesses to the protected data at those points.
