ALSA: drivers: Convert timers to use timer_setup()

2017-10-24T19:01:16+00:00

In preparation for unconditionally passing the struct timer_list pointer to
all timer callbacks, switch to using the new timer_setup() and from_timer()
to pass the timer pointer explicitly.

Annotate hardware config module parameters in sound/drivers/

2017-04-20T11:02:32+00:00

When the kernel is running in secure boot mode, we lock down the kernel to
prevent userspace from modifying the running kernel image.  Whilst this
includes prohibiting access to things like /dev/mem, it must also prevent
access by means of configuring driver modules in such a way as to cause a
device to access or modify the kernel image.

To this end, annotate module_param* statements that refer to hardware
configuration and indicate for future reference what type of parameter they
specify.  The parameter parser in the core sees this information and can
skip such parameters with an error message if the kernel is locked down.
The module initialisation then runs as normal, but just sees whatever the
default values for those parameters is.

Note that we do still need to do the module initialisation because some
drivers have viable defaults set in case parameters aren't specified and
some drivers support automatic configuration (e.g. PNP or PCI) in addition
to manually coded parameters.

This patch annotates drivers in sound/drivers/.

ALSA: drivers: drop owner assignment from platform_drivers

2014-10-20T14:21:59+00:00

A platform_driver does not need to set an owner, it will be populated by the
driver core.

ALSA: drivers: remove __dev* attributes

2012-12-07T06:34:32+00:00

CONFIG_HOTPLUG is going away as an option.  As result the __dev*
markings will be going away.

Remove use of __devinit, __devexit_p, __devinitdata, __devinitconst,
and __devexit.

sound: Add module.h to the previously silent sound users

2011-10-31T23:31:21+00:00

Lots of sound drivers were getting module.h via the implicit presence
of it in  but we are going to clean that up.  So
fix up those users now.
