X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=538e7a004bf960c96c7e9eb836b59989eb5f5b7f;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git V4L/DVB (10102): uvcvideo: Ignore interrupt endpoint for built-in iSight webcams. Built-in iSight webcams have an interrupt endpoint but spit proprietary data that don't conform to the UVC status endpoint messages. Don't try to handle the interrupt endpoint for those cameras.
