Subject: [PATCH 65/65] media: v4l2-ioctl: Stop passing fh pointer to ioctl
handlers
From: Laurent Pinchart <laurent.pinchart@...asonboard.com>
Now that all drivers access the v4l2_fh from the file structure, there
is no need to pass it as an explicit argument to ioctl handlers. Set the
argument to NULL in the w__video_do_ioctl(), and drop the name of the
void *fh argument in the ioctl handler declarations to indicate it is
not used.
The argument could be removed altogether with a mechanical change
(probably using coccinelle), but there are plans to pass a new argument
to the ioctl handlers in the near future. The tree-wide change to remove
the argument, only to add another one soon after, would be too much
churn.
