Linux kernel source tree
bd2355b8ef
Discovered using w_scan when scanning DVB-T/T2: When w_scan goes from -T to -T2, it does so without stopping the frontend using .sleep. Due to this, the demod operation mode isn't re-setup, but as it still is in STATE_ACTIVE_TC, PLP and T2 Profile are set up, but only retune_active() is called, leaving the demod in T mode, thus not operable on any T2 frequency. Fix this by putting the demod to sleep if priv->system isn't equal to p->delsys. To properly accomplish this, sleep_tc() is split into sleep_tc() and shutdown_tc(), where sleep_tc() will only perform the sleep operation, while shutdown_tc() additionally performs the full demod shutdown (to keep the behaviour when the .sleep FE_OP is called).

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
