The unsigned integer nfuncs is being error checked with a value less or equal to zero; this is always false if of_get_child_count returns a -ve for an error condition since nfuncs is not signed. Fix this by making variables nfuncs and i signed integers. Detected with Coccinelle: drivers/pinctrl/freescale/pinctrl-imx.c:620:6-12: WARNING: Unsigned expression compared with zero: nfuncs <= 0 Cc: Linus Walleij <linus.walleij@linaro.org> Reported-by: Colin Ian King <colin.king@canonical.com> Signed-off-by: Dong Aisheng <aisheng.dong@nxp.com> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
