From 3b82f5e352df73dbfba4c205e5a247749c4f21c3 Mon Sep 17 00:00:00 2001 From: Mauro Carvalho Chehab Date: Fri, 2 Jan 2009 18:34:28 -0200 Subject: Missing v4l2_prio_close in radio_release From: Udo Steinberg The radio_release function of the BTTV driver is missing a call to v4l2_prio_close. As a result, after the radio device has been opened at least once (e.g., by HAL during bootup), v4l2_priority will never drop below V4L2_PRIORITY_INTERACTIVE again. With the following patch against 2.6.28, applications that run with V4L2_PRIORITY_BACKGROUND are able to open devices again. Previous Linux versions are affected as well.
