From 73d0d3c8671190ea982a8e79a7c79fbfe88f8f47 Mon Sep 17 00:00:00 2001 From: Marcel Holtmann Date: Sun, 4 Oct 2015 23:34:01 +0200 Subject: [PATCH] Bluetooth: Move HCI_RUNNING check into hci_send_frame In all callbacks for hdev->send the status of HCI_RUNNING is checked. So instead of repeating that code in every driver, move the check into the hci_send_frame function before calling hdev->send.
