From 74292d5ac289ff5ec8b565889aaeab332e709099 Mon Sep 17 00:00:00 2001 From: Marcel Holtmann Date: Sun, 6 Jul 2014 15:50:27 +0200 Subject: [PATCH] Bluetooth: Enforce providing hdev->send driver callback The hdev->send driver callback is mandatory to be provided by a driver before calling hci_register_dev. So enforce it and return EINVAL in case it is not available. All existing drivers are providing this callback anyway, so this is just an extra sanity check.
