The device ignore the rx filters during the scan operation. wfx_configure_filter() acquires scan_lock to reflect this restriction. However, it is not really necessary since mac80211 don't try to configure Rx filters during scan. However, the things are changing. The scan operation is going to be used to implement remain-on-channel. In this case, wfx_configure_filter() can be called during the scan. Currently, this scenario generate a delay that end with a timeout in the upper layers. For the final user, some scenario of the EasyConnect specification end with a failure. So, avoid acquiring the scan_lock and just return.

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.
