cdd861d68d ns83820: spin_lock_irq() => spin_lock()
This is essentially cosmetic.  At this point the IRQs are already
disabled because we called spin_lock_irq(&dev->rx_info.lock).

The real bug here was fixed back in 2006 in 3a10ccebe: "[PATCH] lock
validator: fix ns83820.c irq-flags bug".  Prior to that patch, it was
a "spin_lock_irq is not nestable" type bug.  The 2006 patch changes the
unlock to not re-enable IRQs, which eliminates the potential deadlock.

But this bit was missed.  We should change the lock function as well so
it balances nicely.

ccc901ee58 tipc: Simplify bearer shutdown logic
Optimize processing in TIPC's bearer shutdown code, including:

1. Remove an unnecessary check to see if TIPC bearer's can exist.
2. Don't release spinlocks before calling a media-specific disabling
routine, since the routine can't sleep.
3. Make bearer_disable() operate directly on a struct bearer, instead
of needlessly taking a name and then mapping that to the struct.

d3cc71f71a spi/bfin_spi: redo GPIO CS handling
The common SPI layers take care of detecting CS conflicts and preventing
two devices from claiming the same CS.  This causes problems for the GPIO
CS support we currently have as we are using CS0 to mean "GPIO CS".  But
if we have multiple devices using a GPIO CS, the common SPI layers see
multiple devices using the virtual "CS0" and reject any such attempts.

To make both work, we introduce an offset define.  This represents the
max number of hardware CS values that the SPI peripheral supports.  If
the CS is below this limit, we know we can use the hardware CS.  If it's
above, we treat it as a GPIO CS.  This keeps the CS unique as seen by
the common code and prevents conflicts.
