Subject: USB: storage: Remove subclass and protocol overrides from Novatek quirk

From: Alan Stern <st...@rowland.harvard.edu>

commit df5fde297e617041449f603ed5f646861c80000b upstream.

A report from Oleg Smirnov indicates that the unusual_devs quirks
entry for the Novatek camera does not need to override the subclass
and protocol parameters:

[3266355.209532] usb 1-3: new high-speed USB device number 10 using xhci_hcd

[3266355.338821] usb-storage 1-3:1.0: This device (0603,8611,0100 S 06 P 50) has unneeded SubClass and Protocol entries in unusual_devs.h (kernel 6.16.10-arch1-1)
Please send a copy of this message to
<linu...@vger.kernel.org> and <usb-s...@lists.one-eyed-alien.net>

The overrides are harmless but they do provoke the driver into logging
this annoying message. Update the entry to remove the unneeded entries.
