patch "USB: storage: Remove subclass and protocol overrides from Novatek" added to usb-linus

[gregkh]

This is a note to let you know that I've just added the patch titled

    USB: storage: Remove subclass and protocol overrides from Novatek

to my usb git tree which can be found at
    git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb.git
in the usb-linus branch.

The patch will show up in the next release of the linux-next tree
(usually sometime within the next 24 hours during the week.)

The patch will hopefully also be merged in Linus's tree for the
next -rc kernel release.

If you have any questions about this process, please let me know.

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

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
[3266355.333031] usb 1-3: New USB device found, idVendor=0603, idProduct=8611, bcdDevice= 1.00
[3266355.333040] usb 1-3: New USB device strings: Mfr=1, Product=2, SerialNumber=3

[3266355.333047] usb 1-3: SerialNumber: 966110000000100
[3266355.338621] usb-storage 1-3:1.0: USB Mass Storage device detected
[3266355.338817] usb-storage 1-3:1.0: Quirks match for vid 0603 pid 8611: 4000
[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
<linux-usb@vger.kernel.org> and <usb-storage@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.
