Dan Carpenter cab15e2e70 usb: fotg210-hcd: delete an incorrect bounds test
[ Upstream commit 7fbcd195e2b8cc952e4aeaeb50867b798040314c ]

Here "temp" is the number of characters that we have written and "size"
is the size of the buffer.  The intent was clearly to say that if we have
written to the end of the buffer then stop.

However, for that to work the comparison should have been done on the
original "size" value instead of the "size -= temp" value.  Not only
will that not trigger when we want to, but there is a small chance that
it will trigger incorrectly before we want it to and we break from the
loop slightly earlier than intended.

This code was recently changed from using snprintf() to scnprintf().  With
snprintf() we likely would have continued looping and passed a negative
size parameter to snprintf().  This would have triggered an annoying
WARN().  Now that we have converted to scnprintf() "size" will never
drop below 1 and there is no real need for this test.  We could change
the condition to "if (temp <= 1) goto done;" but just deleting the test
is cleanest.

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.
