* module: remove never implemented MODULE_SUPPORTED_DEVICELeon Romanovsky2021-03-178-8/+0
| | | | | | | | | | MODULE_SUPPORTED_DEVICE was added in pre-git era and never was implemented. We can safely remove it, because the kernel has grown to have many more reliable mechanisms to determine if device is supported or not.

* ALSA: Convert strlcpy to strscpy when return value is unusedJoe Perches2021-01-082-2/+2

* ALSA: aloop: Constify ops structsRikard Falkeborn2020-11-211-3/+3
| | | | | | | | | | | The only usage of the ops field in the loopback_cable struct is to call its members, the field it self is never changed. Make it a pointer to const. This allows us to constify two static loopback_ops structs to allow the compiler to put them in read-only memory.

* ALSA: aloop: Replace tasklet with workTakashi Iwai2020-09-091-12/+11
| | | | | | | | | | | | | The tasklet is an old API that should be deprecated, usually can be converted to another decent API. In aloop driver, a tasklet is still used for offloading the timer event task. It can be achieved gracefully with a work queued, too. This patch replaces the tasklet usage in aloop driver with a simple work. Link: https://lore.kernel.org/r/20200903104131.21097-6-tiwai@suse.de Signed-off-by: Takashi Iwai <tiwai@suse.de>
* ALSA: pcsp: Replace tasklet with workTakashi Iwai2020-09-091-7/+5
| | | | | | | | | | | | | | | | | The tasklet is an old API that should be deprecated, usually can be converted to another decent API. This patch replaces the usage of tasklet in pcsp driver with a simple work. In pcsp driver, a global tasklet is used for offloading the period-elapse handling in the hrtimer callback (introduced in commit 96c7d478efad "ALSA: pcsp - Fix locking messes in snd-pcsp"). It can be achieved gracefully with a work queued in the high-prio system workqueue. This also changes tasklet_kill() with cancel_work_sync() in the sync_stop callback, which is anyway better to assure canceling the pending tasks.

During the ALSA developer meetup at ELC-E 2018 in Edinburgh, a decision was made to go with this approach for keeping best compatibility with existing source code, and then I failed to follow up by resending the patches. Now I have patches for all remaining time_t uses in the kernel, so it's absolutely time to revisit them. I have done more review of the patches myself and found a couple of minor issues that I have fixed up, otherwise the series is still the same as before. Conceptually, the idea of these patches is: - 64-bit applications should see no changes at all, neither compile-time nor run-time. - 32-bit code compiled with a 64-bit time_t currently does not work with ALSA, and requires kernel changes and/or sound/asound.h changes - Most 32-bit code using these interfaces will work correctly on a modified kernel, with or without the uapi header changes. - 32-bit code using SNDRV_TIMER_IOCTL_TREAD requires the updated header file for 64-bit time_t support - 32-bit i386 user space with 64-bit time_t is broken for SNDRV_PCM_IOCTL_STATUS, SNDRV_RAWMIDI_IOCTL_STATUS and SNDRV_PCM_IOCTL_SYNC_PTR because of i386 alignment. This is also addressed by the updated uapi header. - PCM mmap is currently supported on native x86 kernels (both 32-bit and 64-bit) but not for compat mode. This series breaks the 32-bit native mmap support for 32-bit time_t, but instead allows it for 64-bit time_t on both native and compat kernels. This seems to be the best trade-off, as mmap support is optional already, and most 32-bit code runs in compat mode anyway. - I've tried to avoid breaking compilation of 32-bit code as much as possible. Anything that does break however is likely code that is already broken on 64-bit time_t and needs source changes to fix them.
