mwifiex: wakeup main thread to handle command queued
We miss to wakeup main thread after adding command to cmd pending queue at follwing places. These commands are handled later when main thread is woken up for handling an interrupt for sleep event from firmware. This adds worst case delay of 50msec. 1) We don't wakeup main thread when asynchronous command is added to cmd pending queue. Move queue_work() call from mwifiex_wait_queue_complete() to mwifiex_send_cmd_async() to wakeup main thread for sync as well as async commands. 2) Scan operation is triggered due to following reasons a) request from user (ex. "iw scan" command) b) Scan performed by driver internally. In first case main thread is woken up when first scan command is queued in cmd pending queue (we don't need to wakeup main thread for subsequent scan commands, because they are queued in scan command response handler), but it is not done for second case. queue_work() is moved inside mwifiex_scan_networks() to handle both the cases.
