Subject: common/usb_storage.c: Clean up usb_storage_probe()
X-Git-Tag: v2016.01-rc1~111^2~6
X-Git-Url: https://git.sur5r.net/?a=commitdiff_plain;h=f5fb78a2748af0d532110cc4f03912b6b30f8761;p=u-boot

common/usb_storage.c: Clean up usb_storage_probe()

We have the protocol and subclass variables which are used only in
disabled debug code.  This code dates back to the initial git import and
seemingly dead code so remove it.

This was detected by Coverity (CID 131117)
