Hi,
After commit 9bedc7f ("V4L/DVB (12429): v4l2-ioctl: fix G_STD and G_PARM
default handlers"), radio software using V4L1 stopped to work on a saa7134
card, a git bisect pointed to this commit introducing the regression. All
VIDIOCGTUNER calls on a v4l1 application are returning -EINVAL after this
commit.
Investigating the issue, it turns out that v4l1_compat_get_tuner calls
VIDIOC_G_STD ioctl, but as it is a radio device (saa7134-radio) it now is
returning -EINVAL to user space applications which are being confused about
this.
May be VIDIOC_G_STD change in the commit above should be reverted, or
v4l1_compat_get_tuner changed to not return error with G_STD, or not call
G_STD ioctl for a radio device?
