[PATCH 02/29] MUSB: Blackfin: don't fake blackfin_interrupt() result

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

 



From: Sergei Shtylyov <sshtylyov@xxxxxxxxxxxxx>

Commit a5073b52833e4df8e16c93dc4cbb7e0c558c74a2 (musb_gadget: fix unhandled
endpoint 0 IRQs) misses this change to blackfin.c: stop faking successful
result of blackfin_interrupt() and emitting a debug message on an unhandled
interrupt.
