This change intruduces a wide band speech setting which allows higher
level clients to query the local controller support for wide band speech
as well as set the setting state when the radio is powered off.
Internally, this setting controls if erroneous data reporting is enabled
on the controller.

lets use HCI_WIDEBAND_SPEECH_ENABLED. It might be just me, but when I look at WIDE_BAND compared to WIDEBAND, I prefer the latter.

So this statement is creating a knot in my brain ;)
if (hdev->commands[18] & 0x04) {
bool enabled = hci_dev_test_flag(hdev, HCI_WIDEBAND_SPEECH_ENABLED);
..
cp.err_data_reporting = enabled ? ERR_DATA_REPORTING_ENABLED :
ERR_DATA_REPORTING_DISABLED;
..
}
I would not bother checking the quirk here. I would just configure that setting based on the HCI_WIDEBAND_SPEECH_ENABLED flag. Unless we have controllers that report this command and don’t allow setting the value, then we have to deal with it, but right now I assume that they get the basics of HCI right.
Btw. I am debating a coding style here.
cp.err_data_reporting = enabled ? ERR_DATA_REPORTING_ENABLED
: ERR_DATA_REPORTING_DISABLED;
But I am not even sure that is clearer or cleaner.

I agree the QUIRK check could be avoided, but I'd argue the following
condition is still required to avoid sending a command that otherwise
is not necessary to the controller:
hci_dev_test_flag(hdev, HCI_WIDEBAND_SPEECH_ENABLED) !=
(hdev->err_data_reporting != ERR_DATA_REPORTING_ENABLED). I can
however simplify it by using a bool enabled flag as you suggested.
