Subject: [PATCH 0/2] media: uvcvideo: Followup hwtimestamp patches
The series
https://patchwork.linuxtv.org/project/linux-media/list/?series=12485
was all merged but one patch that Laurent found a bug in the index used.
When I tried the fixed patch I found an integer overflow in the
timestamp calculations. This bug can be triggered with slow framerates.
