From: Jussi Kivilinna Date: Fri, 25 Jan 2008 22:51:45 +0000 (+0200) Subject: Move usbnet.h and rndis_host.h to include/linux/usb X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=3692e94f1559523b84a5a0e65929ee84b276e83f;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git Move usbnet.h and rndis_host.h to include/linux/usb Move headers usbnet.h and rndis_host.h to include/linux/usb and fix includes for drivers/net/usb modules. Headers are moved because rndis_wlan will be outside drivers/net/usb in drivers/net/wireless and yet need these headers. Signed-off-by: Jussi Kivilinna Acked-by: David Brownell Signed-off-by: John W.
