Subject: USB: cdc-acm: fix pipe type of write endpoint
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=c5211187f7ff8e8dbff4ebf7c011ac4c0ffe319c;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

USB: cdc-acm: fix pipe type of write endpoint

If the write endpoint is interrupt type, usb_sndintpipe() should
be passed to usb_fill_int_urb() instead of usb_sndbulkpipe().
