[PATCH v5 06/12] usb: cdns3-ti: grab auxdata from match data

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Current code uses the global `cdns_ti_auxdata` variable as auxiliary
data passed to of_platform_populate(). Use match data to store a
pointer to auxdata.

Current behavior is not changed; it allows future compatibles to provide
different auxiliary data.
