Subject: Bluetooth: hci_bcm4377: Mark bcm4378/bcm4387 as BROKEN_LE_CODED
From: Janne Grunau <j@xxxxxxxxxx>
commit 41e9cdea9c4ab6606ca462ff4ec901a82d022c05 upstream.
bcm4378 and bcm4387 claim to support LE Coded PHY but fail to pair
(reliably) with BLE devices if it is enabled.
On bcm4378 pairing usually succeeds after 2-3 tries. On bcm4387
pairing appears to be completely broken.
