If anyone has any objections, please let me know. ------------------ From: Jinjie Ruan 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: 189d92af707e ("V4L/DVB (13422): gspca - ov534: ov772x changes from Richard Kaswy.")
