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? -- 's Herton -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
