Next: Wireless IBSS on Linux-2.6.34 broken by commit 3bbb9ec946428b96657126768f65487a48dd090c
From: Mike Frysinger on 22 May 2010 22:50
From: Ian Jeffray <ian(a)jeffray.co.uk>

The new MUSB power code needs musb_read_txhubport() to return a value (so
stub it as 0 like the other Blackfin hub funcs). It also needs new helper
functions for saving/restoring context, so change the apparently unused
musb_platform_{suspend,resume} to musb_platform_{save,restore}_context in
the Blackfin code.

Note: i believe this is what we want, but Cliff is free to correct me ;)
