Kees Cook 02aa2a3763 drivers: avoid format string in dev_set_name
Calling dev_set_name with a single paramter causes it to be handled as a
format string.  Many callers are passing potentially dynamic string
content, so use "%s" in those cases to avoid any potential accidents,
including wrappers like device_create*() and bdi_register().

Randy Dunlap 8eae508b7c hsi: fix kernel-doc warnings
Fix kernel-doc warnings in hsi files:

  Warning(include/linux/hsi/hsi.h:136): Excess struct/union/enum/typedef member 'e_handler' description in 'hsi_client'
  Warning(include/linux/hsi/hsi.h:136): Excess struct/union/enum/typedef member 'pclaimed' description in 'hsi_client'
  Warning(include/linux/hsi/hsi.h:136): Excess struct/union/enum/typedef member 'nb' description in 'hsi_client'
  Warning(drivers/hsi/hsi.c:434): No description found for parameter 'handler'
  Warning(drivers/hsi/hsi.c:434): Excess function parameter 'cb' description in 'hsi_register_port_event'

Don't document "private:" fields with kernel-doc notation.
If you want to leave them fully documented, that's OK, but
then don't mark them as "private:".

Carlos Chinea ec1c56ff81 HSI: hsi: Rework hsi_event interface
Remove custom hack and make use of the notifier chain interfaces for
delivering events from the ports to their associated clients.
Clients that want to receive port events need to register their callbacks
using hsi_register_port_event(). The callbacks can be called in interrupt
context. Use hsi_unregestier_port_event() to undo the registration.

Carlos Chinea 6f02b9e9b4 HSI: hsi: Remove controllers and ports from the bus
HSI controllers and ports do not belong to the HSI bus.
Those devices are not supposed to have a driver attached to them.

HSI client structure should be freed on error path after
calling device_registration by dropping a reference to it.

Use the proper release mechanism for hsi_controller and
hsi_ports structures. Free the structures through their
associated device release callbacks.

Carlos Chinea a056ab8c7a HSI: hsi: Introducing HSI framework
Adds HSI framework in to the linux kernel.

High Speed Synchronous Serial Interface (HSI) is a
serial interface mainly used for connecting application
engines (APE) with cellular modem engines (CMT) in cellular
handsets.

HSI provides multiplexing for up to 16 logical channels,
low-latency and full duplex communication.
