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

sched/headers: Prepare to move signal wakeup & sigpending methods from into

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

Replace with globally

2016-12-24T19:46:01+00:00

This was entirely automated, using the script by Al: PATT='^[[:blank:]]*#[[:blank:]]*include[[:blank:]]*' sed -i -e "s!$PATT!#include !" \ $(git grep -l "$PATT"|grep -v ^include/linux/uaccess.h) to do the replacement at the end of the merge window.

sound: oss: Use kernel_read_file_from_path() for mod_firmware_load()

2016-07-26T08:38:03+00:00

Since recently we have kernel_read_file_from_path(), and it's doing the same thing as our own home-baked mod_firmware_load(). Let's use the official API function and clean up the old code. 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: avoid time_t usage

2016-06-17T14:31:19+00:00

We want to remove all time_t users from the kernel because of y2038 compatibility. This particular instance does not even use time_t to store a seconds value, so we can simply use 'unsigned int', which seems more fitting anywhere. The same code is used in two OSS files.

sound: oss: Use setup_timer and mod_timer.

2016-05-17T16:02:20+00:00

The function setup_timer combines the initialization of a timer with the initialization of the timer's function and data fields. The mulitiline code for timer initialization is now replaced with function setup_timer. Also, quoting the mod_timer() function comment: -> mod_timer() is a more efficient way to update the expire field of an active timer (if the timer is inactive it will be activated). Use setup_timer() and mod_timer() to setup and arm a timer, making the code compact and aid readablity. Signed-off-by: Muhammad Falak R Wani Signed-off-by: Takashi Iwai

sound/oss: remove VIRT_TO_BUS dependency

2015-12-09T13:40:51+00:00

The OSS sound drivers used to rely on virt_to_bus(), but don't any more, so we can remove the Kconfig dependency. As a lot of architectures don't provide VIRT_TO_BUS any more, removing the dependency in sounds/oss/ would make the deprecated drivers appear there, which we probably don't want. Instead I'm replacing the simple dependency with 'VIRT_TO_BUS || RPC || NETWINDER' so we can still build these sound drivers for the platforms that need them, but don't change anything on other architectures. As a follow-up, we can remove the virt_to_bus() implementation and Kconfig symbol in the ARM architecture. Signed-off-by: Arnd Bergmann Signed-off-by: Takashi Iwai
