| 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. | |
