[ Upstream commit 1624dead9a4d288a594fdf19735ebfe4bb567cb8 ]
The conditional check for the PLL0 multiplier 'm' used a logical AND
instead of OR, making the range check ineffective. This patch replaces
&& with || to correctly reject invalid values of 'm' that are either
less than or equal to 0 or greater than LPC18XX_PLL0_MSEL_MAX.
This ensures proper bounds checking during clk rate setting and rounding.

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.
