From c4f79214e425ae26ec9c27cc0995122321631b87 Mon Sep 17 00:00:00 2001 From: Paul Elder Date: Tue, 28 Aug 2018 02:45:46 -0400 Subject: uvc: reply with max frame rate in response to UVC_GET_MAX Previously, the interval rate that would be selected and replied to the host in response to UVC_GET_MAX, UVC_GET_MIN, and UVC_GET_DEF were all the same and were the first interval rate. Assuming the interval rates are sorted in ascending order, this means that UVC_GET_MAX would always yield the minimum interval rate. Modify the call to uvc_fill_streaming_control such that UVC_GET_MAX will yield the maximum interval rate.
