From: Udo Steinberg Date: Fri, 2 Jan 2009 20:34:28 +0000 (-0300) Subject: V4L/DVB (10173): Missing v4l2_prio_close in radio_release X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=b15dd79ea06b04a7ecee95f62ce7b6a3547dbb0a;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git V4L/DVB (10173): Missing v4l2_prio_close in radio_release 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.
