[PATCH 22/45] USB: musb: fix warnings in Blackfin regs

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

 



From: Mike Frysinger <vapier@xxxxxxxxxx>

The recent commit "usb: musb: Add context save and restore support" added
some stubs for the Blackfin code so things would compile, but it also
added a bunch of warnings due to missing return statements.
