Shenwei Wang 8dfd00bfd5 tty: serial: fsl_lpuart: adjust buffer length to the intended size 
[ Upstream commit f73fd75055 ]

Based on the fls function definition provided below, we should not
subtract 1 to obtain the correct buffer length:

fls(0) = 0, fls(1) = 1, fls(0x80000000) = 32.

README 

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.
