[PATCH v2 3/7] media: subdev: remove VIDIOC_DQEVENT_TIME32 handling

[Arnd Bergmann <arnd@kernel.org>]

From: Arnd Bergmann <arnd@arndb.de>

Converting the VIDIOC_DQEVENT_TIME32/VIDIOC_DQEVENT32/
VIDIOC_DQEVENT32_TIME32 arguments to the canonical form is done in common
code, but for some reason I ended up adding another conversion helper to
subdev_do_ioctl() as well. I must have concluded that this does not go
through the common conversion, but it has done that since the ioctl
handler was first added.

I assume this one is harmless as there should be no way to arrive here
from user space, but since it is dead code, it should just get removed.

Fixes: 1a6c0b36dd19 ("media: v4l2-core: fix VIDIOC_DQEVENT for time64 ABI")
