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. Signed-...

Analyze and fix the following issue in the Linux kernel code: Bluetooth: Fix compilation of Marvell driver without debugfs
Problem Details: The Makefile entry for the Marvell driver is broken when it comes to handling the optional DEBUG_FS correctly.

Problem Details: The Marvell driver selects DEBUG_FS and FW_LOADER for its core driver and that is pointless.

Also FW_LOADER is only used within the SDIO driver and so just have that one select the FW_LOADER option. Sign...
