Hello, all
After last convertion of radio drivers to use v4l2_device we have such
code in many radio drivers:
(it's radio-terratec.c for example)
...
static int terratec_open(struct file *file)
{
return 0;
}
static int terratec_release(struct file *file)
{
return 0;
}
...
and
...
static int vidioc_g_input(struct file *filp, void *priv, unsigned int
*i)
{
*i = 0;
return 0;
}
static int vidioc_s_input(struct file *filp, void *priv, unsigned int i)
{
return i ? -EINVAL : 0;
}
...
Such code used in many radio-drivers as i understand.
Is it good to place this empty and almost empty functions in:
(here i see two variants)
1) In header file that be in linux/drivers/media/radio/ directory.
Later, we can move some generic/or repeating code in this header.
2) In any v4l header. What header may contain this ?
?
For what ? Well, as i understand we can decrease amount of lines and
provide this simple generic functions. It's like
video_device_release_empty function behaviour. Maybe not only radio
drivers can use such vidioc_g_input and vidioc_s_input.
Is it worth ?
