   8 commit bd21f0222adab64974b7d1b4b8c7ce6b23e9ea4d upstream.
   9
  10 This patch fixes the chipmunk-like voice that manifets randomly when
  11 using the integrated mic of the Logitech Webcam HD C270.
  12
  13 The issue was solved initially for this device by commit 2394d67e446b
  14 ("USB: add RESET_RESUME for webcams shown to be quirky") but it was then
  15 reintroduced by e387ef5c47dd ("usb: Add USB_QUIRK_RESET_RESUME for all
  16 Logitech UVC webcams"). This patch is to have the fix back.
