Subject: [PATCH 16/47] Bluetooth: Fix complicated assignment of firmware for Marvell devices
The Marvell Bluetooth SDIO driver has a really complicated concept on how
firmware names are assigned to specific device ids. Fix that by doing a
proper structure and assign it to the module device table.
And while at it fix various coding style weirdness that is still present
in this driver.
