    Subject[PATCH 3.16 43/87] USB: Fix chipmunk-like voice when using Logitech C270 for recording audio.
    3.16.75-rc1 review patch.  If anyone has any objections, please let me know.

    ------------------

    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.
