In some cases, free_irq_cpu_rmap() is called while holding a lock

flush_scheduled_work() which ends up waiting for whole system

Support the Creative BT-D1 Bluetooth USB audio device. Before this
patch, Linux had trouble finding the correct USB descriptors and bailed
out with these messages:
no or invalid class specific endpoint descriptor
Now it still prints these messages on hotplug:

Right, until you do something else on the box requiring just the right
amount of memory to overflow the buffer cache w
The address should be bigger than dac_mmap_min_addr, because
a process with CAP_RAWIO can map a vma bellow mmap_min_addr.

Hi Russ,
Is it possible you try this patch on your 2048 cpus ?
Thanks

The following patch adds support for the bluetooth part of
Gigabyte's GC-WB300D PCIe card (combo card with AR9462 WLAN
and ATH3012 BT).
On every boot there is an error from this device:
usb 2-1.7: string descriptor 0 read error: -22
But that doesn't seem to have any negative effect AFAICT.

Hi,
It is good idea add this feature.
1: Can we let the "ret = hwspin_lock_tests(ops, hwlock);" add after
hwspin_lock_register_single have return
succeed, that can avoid test duplicated Or error lockid. Of course, If
this interface is intend to test soc hardware capability only, we can
put it
