+Subject: USB: Fix chipmunk-like voice when using Logitech C270 for recording audio.
+
+From: Marco Zatta <marco@zatta.me>
+
+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.
