Get rid of unnecessary code since this driver supports only one
pixel format. Removing this code will make the transition to the
mbus API easier as well.

Several calls (try_fmt, g_parm among others) changed the current standard
as a side effect of that call. But the standard may only be changed by s_std.

enum_mbus_fmt received an index argument that was defined as an int instead
of an unsigned int. This is now fixed. This had the knock-on effect that the
index argument in the callback get_formats in soc_camera.h also had to be
changed to unsigned int.

Note that this driver is only used by em28xx and that em28xx does not
actually call the enum/try/s_fmt ops of mt9v011. So these functions
have never been tested.
And in fact the driver really implements cropping instead of scaling. So it
seems to be doing the wrong thing :-(

pvrusb2: Delete sysfs class device as the _very_ last step, after
we're sure that all driver contexts have gone away first. This is
important because it appears that there isn't any protection from a
struct device instance reference a deleted struct class instance. The
assumption in the kernel code appears to be that the class instance is
assumed to be around for the life of the device. So we can't let the
class instance go away until all referencing device instances are
gone; this is ensured by delaying removal of the class instance until
after the driver contexts have all gone away. This bug has been
present for a very long time but it didn't apparently become malignant
until recently (probably because of other changes in the kernel).

pvrusb2: Fix oops caused by touching deleted memory after
unregistration. This bug was introduced when we had started using
video_device_node_name() - that function was being called potentially
after the underlying structure (referenced by that function) had been
deleted. The fix rearranges things slightly so that the function is
called before destruction takes place.
