From 362a03ca4747dbbb67758e54df3d2fff6936e984 Mon Sep 17 00:00:00 2001 From: Hans Verkuil Date: Sun, 12 Jun 2011 06:36:41 -0300 Subject: [PATCH] v4l2-ioctl.c: prefill tuner type for g_frequency and [ upstream commit 227690df75382e46a4f6ea1bbc5df855a674b47f ] g/s_tuner The subdevs are supposed to receive a valid tuner type for the g_frequency and g/s_tuner subdev ops. Some drivers do this, others don't. So prefill this in v4l2-ioctl.c based on whether the device node from which this is called is a radio node or not. The spec does not require applications to fill in the type, and if they leave it at 0 then the 'check_mode' call in tuner-core.c will return an error and the ioctl does nothing.
