Subject: usb: musb: pass platform_ops via platform_data
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=f7ec94370f417fedad4db1054228ef958d48b926;p=linux-beck.git

usb: musb: pass platform_ops via platform_data

... then we don't need to export any symbols
from glue layer to musb_core.
