For reading / writing the asd->streaming enum the following rules should be followed: 1. Writers of streaming must hold both isp->mutex and isp->lock. 2. Readers of streaming need to hold only one of the two locks. Not all writers where properly taking both locks this fixes this. In the case of the readers, many readers depend on their caller to hold isp->mutex, add asserts for this And in the case of atomisp_css_get_dis_stat() it is called with isp->mutex held, so there is no need to take the spinlock just for reading the streaming value.

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.
