Wright Feng 09be7546a6 wifi: brcmfmac: fix scheduling while atomic issue when deleting flowring
We should not sleep while holding the spin lock. It makes
'scheduling while atomic' in brcmf_msgbuf_delete_flowring.
And to avoid race condition between deleting flowring and txflow,
we only hold spin lock when seting flowring status to RING_CLOSING.

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.
