Firmware for 0A5C:21E6 in HCD

Hi folks!

I converted this firmware from the origin Windows-Driver for a Lenovo ThinkPad X230.

Information-file:
bcbtums-win7x64-brcm.inf

Related origin firmware:
BCM20702A1_001.002.014.0449.0462.hex

Converted firmware:
BCM20702A0-0a5c-21e6.hcd

Location to load:
/lib/firmware/brcm/BCM20702A0-0a5c-21e6.hcd

Output after successful load:
kernel: Bluetooth: hci0: BCM: patching hci_ver=06 hci_rev=11ce lmp_ver=06 lmp_subver=220e
kernel: Bluetooth: hci0: BCM: firmware hci_ver=06 hci_rev=11ce lmp_ver=06 lmp_subver=220e

Enjoy :-)

I converted this firmware from the origin Windows-Driver for a Lenovo ThinkPad X230.

Nice approach, thanks. But this is not something for the "casual" user. I think we must still get rid of the error message.

My problem isn't with Bluetooth (it work fine without the patch). It's the fact that this error masks all subsequent kernel errors. Due to this being an error (although it really isn't) my kernel gets "tainted" and the reporting of subsequent problems (the ones that really matter to me) is turned off.
