Subject: [PATCH AUTOSEL 6.12 11/23] media: uvcvideo: Force UVC version to 1.0a for 0408:4033

From: Ricardo Ribalda <ribalda@...omium.org>

[ Upstream commit c9df99302fff53b6007666136b9f43fbac7ee3d8 ]

The Quanta ACER HD User Facing camera reports a UVC 1.50 version, but
implements UVC 1.0a as shown by the UVC probe control being 26 bytes
long. Force the UVC version for that device.
