2011-01-03dahdi: Allow spans to advertise if they can provide any timing.Shaun Ruffell
Some spans, specifically dynamic local spans, should never be the timing master since they are dependent on some other timing source driving them. The bit in 'struct dahdi_span' is named cannot provide timing so that by default the other drivers will set it to 0. This is loosely related to issue #13205 but doesn't address any of the other elements of that issue about how to allow the user to configure what the master span order of succession is.

2011-01-03dahdi_dynamic: dynamic drivers should not reference count themselves.Shaun Ruffell
Move the try_module_get/module_put calls from the various dynamic drivers into the "core" dahdi_dynamic.c file itself. This way, a reference count can always be held while calling through the function pointers. This is enabled by adding an .owner field to 'struct dahdi_dynamic_driver'. Dynamic spans are also unique in dahdi in that they require a "dahdi_cfg -s" to stop them and release the references on the modules. This is counterintuitive. This change makes sure they are reference counted just like other spans and on driver unload, if there aren't any open handles from userspace, they will take care of unwinding themselves.

2011-01-03dahdi_dynamic_loc: Do not call dahdi_dynamic_receive on peers before reg.Shaun Ruffell
It's possible for dahdi_dynamic_loc spans to be "peered" before the dahdi_span is fully register. Do not call dahdi_dynamic_receive on any peers before they are fully registered.

2010-09-24Move test for DEFINE_SPINLOCK into include/dahdi/kernel.hShaun Ruffell
The check for DEFINE_SPINLOCK was spread throughout the source tree. If not defined we can just define it in inlucde/dahdi/kernel.h. Now include/dahdi/kernel.h is the only place that references SPIN_LOCK_UNLOCKED (which breaks lockdep checking if DEFINE_SPINLOCK is otherwise defined in the kernel).
