commit d2842dec577900031826dc44e9bf0c66416d7173 upstream.
In set_frame_rate(), select a rate in rate_0 or rate_1 by checking
sd->frame_rate >= r->fps in a loop, but the loop condition terminates when
the index reaches zero, which fails to check the last elememt in rate_0 or
rate_1.
Check for >= 0 so that the last one in rate_0 or rate_1 is also checked.
Fixes: 189d92af70 ("V4L/DVB (13422): gspca - ov534: ov772x changes from Richard Kaswy.")

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.
