Subject: Bluetooth: btbcm: Add firmware table for UART based devices
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=9a0bb57d2d08f1923aeef3af1877ec0b6f3209ba;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

Bluetooth: btbcm: Add firmware table for UART based devices

The Broadcom UART based devices seem to use a little bit different
firmare naming prefix. So add a separate table for these devices.
