From 9b969f93bcef9b3d9e92f1810e22bbd6c344a0e5 Mon Sep 17 00:00:00 2001 From: Michael Grzeschik Date: Sun, 3 Apr 2022 01:27:43 +0200 Subject: usb: gadget: uvc: giveback vb2 buffer on req complete On uvc_video_encode_isoc_sg the mapped vb2 buffer is returned to early. Only after the last usb_request worked with the buffer it is allowed to give it back to vb2. This patch fixes that.
