[ Upstream commit 52bb1cb7118564166b04d52387bd8403632f5190 ] Only CS7 and CS8 seem supported but CSIZE is not sanitized from CS5 or CS6 to CS8. In addition, ASC_CTL_MODE_7BIT_PAR suggests that CS7 has to have parity, thus add PARENB. Incorrect CSIZE results in miscalculation of the frame bits in tty_get_char_size() or in its predecessor where the roughly the same code is directly within uart_update_timeout(). Fixes: c4b058560762 (serial:st-asc: Add ST ASC driver.)

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.
