+Subject: [PATCH] media: uvcvideo: Fixed ktime_t to ns conversion
+
+Commit 828ee8c71950 ("media: uvcvideo: Use ktime_t for timestamps")
+changed to use ktime_t for timestamps. Older Kernels use a struct for
+ktime_t, which requires the conversion function ktime_to_ns to be used on
+some places. With this patch it will compile now also for older Kernel
+versions.
