Move lnext handling from __receive_buf to n_tty_receive_buf_standard. It simplifies the handling as it needs not fetching 'flag' and decrement 'count' in __receive_buf. Instead, all this is left up to the loop in n_tty_receive_buf_standard which already does that. This way, no need to repeat the action when n_tty_receive_char_special returns true -- ldata->lnext is set there in that case, so the 'if (ldata->lnext)' check is sufficient. The next patch will switch n_tty_receive_char_special to return 'void'. The result is much simplified code flow.

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.
