2010-12-07dahdi: Prevent unloadable module on failed open.Shaun Ruffell
If chan->span->ops->open() fails then the reference count of the module implementing the board driver will not be decremented. The result is a module that would always be "in use" and unloadable. This change makes sure to release that reference when open failed.

2010-12-07xpd_pri: Remove pointless hooksig span opTzafrir Cohen

2010-12-07xpd_pri: ignore DAHDI_VMWI and DAHDIVMWI_CONFIGTzafrir Cohen
This fixes an annoying, though harmless issue: if Asterisk decides to send voicemail messages to a channel (CAS, configured as FXS), We can't do anything useful with them. So ignore them to avoid scary-looking messages (from report_bad_ioctl()).

2010-12-02wctdm24xxp, wcte12xp: Close a few potential resource assignment leaks.Shaun Ruffell
There were some routes through the failure paths in __voicebus_init() where a registered memory region was not subsequently released. This change closes those paths. The result would be on subsequent loads of the driver after hitting the failure condition you would see "IO Registers are in use by another module." in dmesg. request_mem_region/release_mem_region should most likely be converted to devm_request_region and devm_release_region introduced in 2.6.20 (commit 9ac7849e35f705830f7b016ff272b0ff1f7ff759) which was introduced for reasons just such as this.

2010-12-01wctdm24xxp: Replace interruptible_sleep_on() with msleep when delaying.Shaun Ruffell
There were several cases where interruptible_sleep_on() was being used as a ms timer, since the assumption is that the board will interrupt at even 1ms intervals. We can replace these cases with msleep directly to clarify that we're just waiting.

2010-11-25dahdi: A little cleanup in the dahdi_ioctl_iomux function.Shaun Ruffell
The primary change is to make clear that the wait result is not ever to be returned by the function.

2010-09-24dahdi: Remove bigzaplock by converting chan_lock to spinlock_t.Shaun Ruffell
The bigzaplock was used to prevent changes to all the channels during masterspan processing while conference parameters were changing. The master span processing also took a global lock out on the chan_lock to prevent new channels from being registered or unregistered during processing. Instead of grabbing both those locks, just changing the semantics of chan_lock to those of bigzaplock seems to fit the bill and removes another lock from the driver (and saves ~10 ns on a 2.40 GHz Xeon in prcocess_masterspan) chan_lock is a candidate for conversion to RCU but usage in conferencing (bigzaplock type usage) needs to be audited carefully before conversion.
