Nathan Chancellor 4a8c5f25c6 USB: gadget: udc: s3c2410_udc: Remove pointless NULL check in s3c2410_udc_nuke
[ Upstream commit 7a0fbcf7c308920bc6116b3a5fb21c8cc5fec128 ]

Clang warns:

drivers/usb/gadget/udc/s3c2410_udc.c:255:11: warning: comparison of
address of 'ep->queue' equal to a null pointer is always false
[-Wtautological-pointer-compare]
        if (&ep->queue == NULL)
             ~~~~^~~~~    ~~~~
1 warning generated.

It is not wrong, queue is not a pointer so if ep is not NULL, the
address of queue cannot be NULL. No other driver does a check like this
and this check has been around since the driver was first introduced,
presumably with no issues so it does not seem like this check should be
something else. Just remove it.

Commit afe956c577b2d ("kbuild: Enable -Wtautological-compare") exposed
this but it is not the root cause of the warning.

Fixes: 3fc154b6b8 ("USB Gadget driver for Samsung s3c2410 ARM SoC")

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.
