Subject: [PATCH] USB: Fix chipmunk-like voice when using Logitech C270 for recording audio.
Git-commit: bd21f0222adab64974b7d1b4b8c7ce6b23e9ea4d
Patch-mainline: v5.2-rc5
References: bsc#1051510

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.
