usb: core: add quirk for Alcor Link AK9563 smartcard reader
The Alcor Link AK9563 smartcard reader used on some Lenovo platforms doesn't work. If LPM is enabled the reader will provide an invalid usb config descriptor. Added quirk to disable LPM. Verified fix on Lenovo P16 G1 and T14 G3 Tested-by: Miroslav Zatko <mzatko@mirexoft.com> Tested-by: Dennis Wassenberg <dennis.wassenberg@secunet.com> Cc: stable@vger.kernel.org Signed-off-by: Dennis Wassenberg <dennis.wassenberg@secunet.com> Signed-off-by: Mark Pearson <mpearson-lenovo@squebb.ca> Link: https://lore.kernel.org/r/20230208181223.1092654-1-mpearson-lenovo@squebb.ca Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
