The bluetooth module in the Asus UX31/UX21 is based on Atheros AR3012
and requires a firmware to be uploaded before it's usable.

Fix up conflicts with 'struct sysdev' removal from various platform
drivers that got changed:
- arch/arm/mach-exynos/cpu.c
- arch/arm/mach-exynos/irq-eint.c
- arch/arm/mach-s3c64xx/common.c
- arch/arm/mach-s3c64xx/cpu.c
- arch/arm/mach-s5p64x0/cpu.c
- arch/arm/mach-s5pv210/common.c
- arch/arm/plat-samsung/include/plat/cpu.h
- arch/powerpc/kernel/sysfs.c
and fix up cpu_is_hotpluggable() as per Greg in include/linux/cpu.h
This converts the drivers in drivers/bluetooth/* to use the
module_usb_driver() macro which makes the code smaller and a bit
simpler.
Added bonus is that it removes some unneeded kernel log messages about
drivers loading and/or unloading.

We are allowed to sleep here so no need to use GFP_ATOMIC. The caller
(ath3k_probe) calls request_firmware() which definitely sleeps. Hence, we should
avoid using GFP_ATOMIC.

This makes it much easier for the users to understand why the driver
refuses to load when the firmware is unavailable.

The new Ath3k needs to download patch and radio table,
and it keeps same PID/VID even after downloading the patch and radio
table. This patch is to use the bcdDevice (Device Release Number) to
judge whether the chip has been patched or not. The init bcdDevice
value of the chip is 0x0001, this value increases after patch and
radio table downloading.

In commit 86e09287e4, to reduce memory
usage, the functions of the ath3k module were rewritten to release the
firmware blob after it has been loaded (successfully or not).
The resuting code has some redundancy and the compiler can potentially
produce better code if we omit a function call that is unconditionally
executed in
,----
| if (ath3k_load_firmware(udev, firmware)) {
| release_firmware(firmware);
| return -EIO;
| }
| release_firmware(firmware);
|
| return 0;
| }
`----
It may also be argued that the rewritten code becomes easier to read,
and also to see the code coverage of the snippet in question.
