From bcd158de94238d90adf7275548f0aaf2de724ab1 Mon Sep 17 00:00:00 2001 From: Sylwester Nawrocki Date: Sat, 1 Oct 2011 11:13:59 -0300 Subject: [media] v4l: Add VIDIOC_LOG_STATUS support for sub-device nodes The VIDIOC_LOG_STATUS ioctl allows to dump the current status of a driver to the kernel log. Currently this ioctl is only available at video device nodes and the subdevs rely on the host driver to expose their core.log_status operation to user space. This patch adds VIDIOC_LOG_STATUS support at the sub-device nodes, for standalone subdevs that expose their own /dev entry.
