Subject: wlan: Avoid abort due to access of deinitialised socket
|
|
|
|
If driver initialization fails after nl initialization,
|
|
driver tries to stop PE by posting the message to MC
|
|
thread which in turn tries to send a message to the
|
|
ptt App, by this time the socket would have been
|
|
de-initialized due to which abort occurs.
|
|
|
|
Avoid sending any message during load unload in progress.
|
|
Reduce the min number of logging buffers to support low
|
|
memory devices and use vmalloc instead for logging buffer
|
|
allocation.
