From 123c26311859b1b1848b1cfe80feac228fd5afb5 Mon Sep 17 00:00:00 2001 From: Luiz Augusto von Dentz <luiz.von.dentz@intel.com> Date: Thu, 20 Jul 2023 15:16:32 -0700 Subject: Bluetooth: btusb: Move btusb_recv_event_intel to btintel btusb_recv_event_intel is specific to Intel controllers therefore it shall be placed inside btintel.c so btusb don't have a mix of vendor specific code with the generic parts.
