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.

ALSA: drivers: mpu401: constify pnp_device_id

2017-08-17T10:42:14+00:00

pnp_device_id are not supposed to change at runtime. All functions
working with pnp_device_id provided by  work with
const pnp_device_id. So mark the non-const structs as const.

ALSA: mpu401: Adjust four checks for null pointers

2017-08-12T21:35:48+00:00

The script “checkpatch.pl” pointed information out like the following.

Comparison to NULL could be written !…

Thus fix the affected source code places.

ALSA: mpu401: Use common error handling code in snd_mpu401_uart_new()

2017-08-12T21:35:24+00:00

Add a jump target so that a bit of exception handling can be better reused
at the end of this function.

ALSA: mpu401: Delete an error message for a failed memory allocation in snd_mpu401_uart_new()

2017-08-12T21:35:06+00:00

Omit an extra message for a memory allocation failure in this function.

This issue was detected by using the Coccinelle software.

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/.

Now snd_rawmidi_ops is maintained as a const pointer in snd_rawmidi,
we can constify the definitions.

ALSA: drivers: mpu401: drop owner assignment from platform_drivers

2014-10-20T14:22:00+00:00

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