This patch removes two locks in the rkisp1_stats struct: - The mutex 'wq_lock' that is used to protect the buffers list 'stat' - The spin_lock 'irq_lock' that is used to protect the variable 'is_streaming' It replaces them with one spin_lock 'lock' that protects both the buffers list and the 'is_streaming' variable. In later patch the reading of the statistics will move to the isr so there will be no need for the mutex 'wq_lock' Signed-off-by: Dafna Hirschfeld <dafna.hirschfeld@collabora.com> Acked-by: Helen Koike <helen.koike@collabora.com> Signed-off-by: Hans Verkuil <hverkuil-cisco@xs4all.nl> Signed-off-by: Mauro Carvalho Chehab <mchehab+huawei@kernel.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.
