This patch fix the broken LED quirk for Intel legacy ROM devices.
fix*es*
Excuse my ignorance, but what are Intel legacy ROM devices? Maybe also
mention the IDs 0x0a2a and 0x0aa7 in the commit message?
Legacy device sends the SW RFKILL while shutting down the device (like
HCI interface down) to turn off the LED by putting the device in assert.
Once the SW RFKILL is on, it needs the HCI_Reset to exit from the SW
RFKILL state. This patch checks the quirk and send the HCI_Reset before
send*s*
sending the HCI_Intel_Read_Version command.
Is that document in some datasheet/specification? If so, please mention it.
Also, in the commit message summary you write “Fix”. If it fixes an old
commit, please add a Fixes: tag.

I have a Dell Latitude E7250 with the 8087:0a2a. How can I test this?
