From 6322f377bc4a0e3dac040c1c6d01761514f42187 Mon Sep 17 00:00:00 2001 From: Fabian Schindlatz Date: Mon, 1 Jul 2019 22:57:13 +0200 Subject: Bluetooth: hci_ll: Refactor download_firmware MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Extract the new function send_command_from_firmware from download_firmware, which helps with the readability of the switch statement. This way the code is less deeply nested and also no longer exceeds the 80 character limit.
