From 1ffa4ad042c3151b57ba3f316d5582166f964537 Mon Sep 17 00:00:00 2001 From: Marcel Holtmann Date: Tue, 16 Sep 2014 05:33:33 +0200 Subject: [PATCH] Bluetooth: btusb: Split fragement receiption into separate functions The actual packet reassembly should be done inside the driver. To allow this to happen cleanly in future patches, split the fragment reception into its own functions.
