Return value of irq_of_parse_and_map() is unsigned int, with 0
indicating failure, so testing for negative result never works.

The module documents, that 1 is the default, but
it actually isn't. This updates the module to use
pm=1 as default.

Remove the use of the IRQF_DISABLED flag
from drivers/hsi/clients/nokia-modem.c

It's a NOOP since 2.6.35 and it will be removed soon.

Pull HSI changes from Sebastian Reichel:
 "Misc fixes in SSI related drivers"

* tag 'hsi-for-3.17' of git://git.kernel.org/pub/scm/linux/kernel/git/sre/linux-hsi:
  HSI: omap_ssi: Fix return value check in ssi_debug_add_ctrl()
  HSI: omap_ssi_port: Fix return value check in ssi_debug_add_port()
  HSI: ssi_protocol: Fix sparse non static symbol warning
  drivers/hsi/controllers/omap_ssi{,_port}.c: fix failure checks

Fixes the following sparse warning:

drivers/hsi/clients/ssi_protocol.c:904:6: warning:
 symbol 'ssip_port_event' was not declared. Should it be static?

The SSI protocol implementation has an incorrect dependency on the OMAP_SSI
driver, which allows SSI to be built-in while the underlying OMAP_SSI
implementation is a loadable module, causing a link error.

This changes the dependency to the simpler 'depends on OMAP_SSI' that also
ensures that SSI-protocol can only be a module if OMAP_SSI is not built-in.

The Nokia N900's modem is connected via Synchronous Serial Interface (SSI),
which is a legacy version of MIPI's High-speed Synchronous Serial Interface
(HSI).

The handles the GPIOs for enabling and resetting the modem and instanciates
ssi-protocol for data exchange. It does not yet support exchanging voice data
with the modem.
