Subject: r8152: redefine REALTEK_USB_DEVICE
X-Git-Tag: v3.19-rc1~118^2~62
X-Git-Url: http://git.cascardo.eti.br/?a=commitdiff_plain;h=d9a28c5b4c9a69f3036743bed36902b45dd39f1d;p=cascardo%2Flinux.git

r8152: redefine REALTEK_USB_DEVICE

Redefine REALTEK_USB_DEVICE for the desired USB interface for probe().
There are three USB interfaces for the device. USB_CLASS_COMM and
USB_CLASS_CDC_DATA are for ECM mode (config #2). USB_CLASS_VENDOR_SPEC
is for the vendor mode (config #1). However, we are not interesting
in USB_CLASS_CDC_DATA for probe(), so redefine REALTEK_USB_DEVICE
to ignore the USB interface class of USB_CLASS_CDC_DATA.
