Hi Sebastian, > The USB completion callback does not disable interrupts while acquiring > the ->lock. We want to remove the local_irq_disable() invocation from > __usb_hcd_giveback_urb() and therefore it is required for the callback > handler to disable the interrupts while acquiring the lock. > The callback may be invoked either in IRQ or BH context depending on the > USB host controller. > Use the _irqsave variant of the locking primitives. > > Cc: Marcel Holtmann <marcel@xxxxxxxxxxxx> > Cc: Johan Hedberg <johan.hedberg@xxxxxxxxx> > Cc: linux-bluetooth@xxxxxxxxxxxxxxx > Signed-off-by: Sebastian Andrzej Siewior <bigeasy@xxxxxxxxxxxxx> > --- > drivers/bluetooth/btusb.c | 20 ++++++++++++-------- > 1 file changed, 12 insertions(+), 8 deletions(-) patch has been applied to bluetooth-next tree.
