Linux kernel source tree
a32d9c41bd
Now that every ioctl takes care of their power management we can remove the "global" power management. Despite its size, this is a relatively big change. We hope that there are no size effects of it. If there are some specific devices that miss-behave, we can add a small quirk for them. This patch introduces a behavioral change for the uvc "trigger" button. Before the "trigger" button would work as long as userspace has opened /dev/videoX. Now it only works when the camera is actually streaming. We consider that this the most common (if not the only) usecase and therefore we do not think of this as a regression.

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 reStructuredText 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.
