sound: Retire OSS

2017-10-31T10:06:39+00:00

Since no complaints have been raised after disabling the build of OSS (Open Sound System) by the commit 31cbee6a5611 ("sound: Disable the build of OSS drivers"), let's finally drop the whole code and documentation. Some glue codes are still left intact since sound/oss/dmasound stuff remains -- which is an independent implementation solely for m68k, and it's not covered by ALSA yet. Also, a couple of API header files (linux/sound.h and linux/soundcard.h) are kept remaining as well, since the OSS API itself is still supported by ALSA OSS emulation, and applications can refer to these. Where we're at it, some help texts in the top-level Kconfig are adjusted, too (who still needs to specify I/O port in kbuild nowadays?). Reviewed-by: Jaroslav Kysela Signed-off-by: Takashi Iwai

Annotate hardware config module parameters in sound/oss/

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/oss/. Suggested-by: Alan Cox Signed-off-by: David Howells cc: Jaroslav Kysela cc: Takashi Iwai cc: Andrew Veliath cc: alsa-devel@alsa-project.org

sound: oss/ad1848: remove some dead code

2017-01-31T20:41:19+00:00

We never use the irq2dev[] array so we can remove this assignment. Signed-off-by: Dan Carpenter Signed-off-by: Takashi Iwai

sound: oss: Remove useless initialisation

2016-07-12T06:06:10+00:00

Remove useless initialisation of variable whose value is reinitialised later. The Coccinelle semantic patch used to make this change is as follows: @@ type T; identifier x; constant C; expression e; @@ T x - = C ; x = e; Signed-off-by: Amitoj Kaur Chawla Signed-off-by: Takashi Iwai

sound: oss: fix build warning

2015-05-18T08:27:17+00:00

while building with allyesconfig it was giving a build warning about unused variable. declare the variable only if the driver is built as a module. Signed-off-by: Sudip Mukherjee Signed-off-by: Takashi Iwai

sound/oss: Remove uncompilable DBG macro use

2014-04-04T16:20:10+00:00

Most of it duplicates function tracing and one of them has an uncompilable printf %P use. Others have format/argument mismatches. Remove unused DBG1 macro definition Neaten uart401.c use of ok test around this DBG macro removal. Signed-off-by: Joe Perches Signed-off-by: Takashi Iwai

sound: oss: remove __dev* attributes

2012-12-07T06:30:49+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. Signed-off-by: Bill Pemberton Signed-off-by: Takashi Iwai

ALSA: module_param: make bool parameters really bool

2011-12-19T09:34:41+00:00

module_param(bool) used to counter-intuitively take an int. In fddd5201 (mid-2009) we allowed bool or int/unsigned int using a messy trick. It's time to remove the int/unsigned int option. For this version it'll simply give a warning, but it'll break next kernel version. Signed-off-by: Rusty Russell Signed-off-by: Takashi Iwai

sound: oss: rename local change_bits to avoid powerpc bitsops.h definition

2011-07-27T17:16:05+00:00

This collides with powerpc exported functions from bitops.h. Rename the local copy in the oss soundblaster mixer and ad1848 driver. Signed-off-by: Andy Whitcroft Signed-off-by: Takashi Iwai

sound/oss: Adjust confusing if indentation
