Unlike other drivers cp210x have been retrieving the current terminal settings from the device on open and reflecting those in termios. Due to how set_termios() used to be implemented, this saved a few control requests on open but has instead caused problems like broken flow control and has required adding workarounds for swapped line-control in cp2108 and line-speed initialisation on cp2104. This unusual implementation also complicates adding new features for no good reason. Rip out the corresponding code and the above mentioned workarounds and instead initialise the terminal settings unconditionally on open. Signed-off-by: Johan Hovold <johan@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.
