The counts in tty_port_client_operations hooks' are currently represented by all 'int', 'unsigned int', and 'size_t'. Unify them all to unsigned 'size_t' for clarity. Note that size_t is used already in tty_buffer.c. So, eventually, it is spread for counts everywhere and this is the beginning. So the two changes namely: * ::receive_buf() is called from tty_ldisc_receive_buf(). And that expects values ">= 0" from ::receive_buf(), so switch its rettype to size_t is fine. tty_ldisc_receive_buf() types will be changed separately. * ::lookahead_buf()'s count comes from lookahead_bufs() and is already 'unsigned int'.

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.
