[PATCH 2/5] Bluetooth: Remove unnecessary include export.h

[Syam Sidhardhan]

For files only using THIS_MODULE and/or EXPORT_SYMBOL, map
them onto including export.h -- or if the file isn't even
using those, then just delete the include.

[PATCH v1 5/5] Bluetooth: Fix L2CAP dynamic PSM bind issue

[Syam Sidhardhan]

Dynamic PSM choosen by the kernel should bound to either BDADDR_ANY
or the same adapter address(not both) for a particular adapter.

The problem here is by giving PSM 0, the kernel should return the first
available PSM in the non-reserverd space, but since we reuse the same
code to do the matching it end up given both Obexd and HDP the same
PSM.

Provid a helper function to handle the dymanic PSM auto selection.

have you actually check this on other architectures like PowerPC or
Sparc?

for these ones, break the 80 chars rule. In this case that is
acceptable.

this is a bad name. No idea what kind of meaning "dyna" has.

And btw. there is no such thing as dynamic PSM. It has nothing dynamic
about it. It is an auto-selected PSM. And in the end, it just selects
the next free one.

This code needs a comment on how it is suppose to work and why it is

I have checked it only for Arm and i686 arch. I do not have other 
environment to check.
If any one has other architectures environment ready, kindly do the build 
and ack for it. Apart from
build, I have cross checked the code once gain to make sure that nothing 
breaks.
