If anyone has any objections, please let me know. ------------------ From: Marco Zatta commit bd21f0222adab64974b7d1b4b8c7ce6b23e9ea4d upstream. This patch fixes the chipmunk-like voice that manifets randomly when using the integrated mic of the Logitech Webcam HD C270. The issue was solved initially for this device by commit 2394d67e446b ("USB: add RESET_RESUME for webcams shown to be quirky") but it was then reintroduced by e387ef5c47dd ("usb: Add USB_QUIRK_RESET_RESUME for all Logitech UVC webcams"). This patch is to have the fix back.
