In wilc_wlan_handle_txq(), mutex unlock was called without acquiring it. Also error code for full VMM condition was incorrect as discussed in [1]. Now used a proper code to indicate VMM is full, for which transfer to VMM is required again. 'wilc_wlan_handle_txq()' should be called again if the VMM space was full earlier or otherwise based on 'txq_event' signal. 1. https://lore.kernel.org/driverdev-devel/20191113183322.a54mh2w6dulklgsd@kili.mountain/ Signed-off-by: Ajay Singh <ajay.kathat@microchip.com> Link: https://lore.kernel.org/r/20200123182129.4053-2-ajay.kathat@microchip.com Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
