[ Upstream commit15d90a6ae9] earth-pt1 driver was decomposed/restructured by the commitb732539efd("media: dvb: earth-pt1: decompose pt1 driver into sub drivers"), but it introduced a problem regarding concurrent streaming: Opening a new terrestial stream stops the reception of an existing, already-opened satellite stream. The demod IC in earth-pt1 boards contains 2 pairs of terr. and sat. blocks, supporting 4 concurrent demodulations, and the above problem was because the config of a terr. block contained whole reset/init of the pair blocks, thus each open() of a terrestrial frontend wrongly cleared the config of its peer satellite block of the demod. This whole/pair reset should be executed earlier and not on each open().

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.
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.
