While converting emi62 to use request_firmware(), the driver was also
changed to use the ihex helper functions.  However, this broke the loading
of the FPGA firmware because the code tries to access the addr field of
the EOF record which works with a plain array that has an empty last
record but not with the ihex helper functions where the end of the data is
signaled with a NULL record pointer, resulting in:

BUG: unable to handle kernel NULL pointer dereference at (null)
IP: [<f80d248c>] emi62_load_firmware+0x33c/0x740 [emi62]

This can be fixed by changing the loop condition to test the return value
of ihex_next_binrec() directly (like in emi26.c).

This patch (as1315) fixes some bugs in the USB core authorization
code:

	usb_deauthorize_device() should deallocate the device strings
	instead of leaking them, and it should invoke
	usb_destroy_configuration() (which does proper reference
	counting) instead of freeing the config information directly.

	usb_authorize_device() shouldn't change the device strings
	until it knows that the authorization will succeed, and it should
	autosuspend the device at the end (having autoresumed the
	device at the start).

	Because the device strings can be changed, the sysfs routines
	to display the strings must protect the string pointers by
	locking the device.

This patch (as1314) renames usb_configure_device() and

v2 - Set proper mode type flags
v3 - Note that this is not neceesarily the exact panel mode,
but an approximation based on the cvt formula.  For these
