Subject: Bluetooth: Add missing check for BREDR_ENABLED flag in update_class()
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=f87ea1dabb4b0e50f0c3d7140d89f1bb697a1676;p=linux-beck.git

Bluetooth: Add missing check for BREDR_ENABLED flag in update_class()

We shouldn't be sending the HCI_Write_Class_Of_Device command when
BR/EDR is disabled since this is a BR/EDR-only command.
