Simplify the proc fs creation code with new helper functions, snd_card_ro_proc_new() and snd_card_rw_proc_new(). Just a code refactoring and no functional changes. Reviewed-by: Jaroslav Kysela Signed-off-by: Takashi Iwai

ALSA: drivers: Remove superfluous snd_pcm_suspend*() calls

The call of snd_pcm_suspend_all() & co became superfluous since we call it in the PCM PM ops. Let's remove them. Reviewed-by: Jaroslav Kysela Signed-off-by: Takashi Iwai

Merge branch 'timers-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip

2018-01-30T00:50:58+00:00

Pull timer updates from Thomas Gleixner: "The timer departement presents: - A rather large rework of the hrtimer infrastructure which introduces softirq based hrtimers to replace the spread of hrtimer/tasklet combos which force the actual callback execution into softirq context. The approach is completely different from the initial implementation which you cursed at 10 years ago rightfully. The softirq based timers have their own queues and there is no nasty indirection and list reshuffling in the hard interrupt anymore. This comes with conversion of some of the hrtimer/tasklet users, the rest and the final removal of that horrible interface will come towards the end of the merge window or go through the relevant maintainer trees. Note: The top commit merged the last minute bugfix for the 10 years old CPU hotplug bug as I wanted to make sure that I fatfinger the merge conflict resolution myself. - The overhaul of the STM32 clocksource/clockevents driver - A new driver for the Spreadtrum SC9860 timer - A new driver dor the Actions Semi S700 timer - The usual set of fixes and updates all over the place" * 'timers-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (53 commits) usb/gadget/NCM: Replace tasklet with softirq hrtimer ALSA/dummy: Replace tasklet with softirq hrtimer hrtimer: Implement SOFT/HARD clock base selection hrtimer: Implement support for softirq based hrtimers hrtimer: Prepare handling of hard and softirq based hrtimers hrtimer: Add clock bases and hrtimer mode for softirq context hrtimer: Use irqsave/irqrestore around __run_hrtimer() hrtimer: Factor out __hrtimer_next_event_base() hrtimer: Factor out __hrtimer_start_range_ns() hrtimer: Remove the 'base' parameter from hrtimer_reprogram() hrtimer: Make remote enqueue decision less restrictive hrtimer: Unify remote enqueue handling hrtimer: Unify hrtimer removal handling hrtimer: Make hrtimer_force_reprogramm() unconditionally available hrtimer: Make hrtimer_reprogramm() unconditional hrtimer: Make hrtimer_cpu_base.next_timer handling unconditional hrtimer: Make the remote enqueue check unconditional hrtimer: Use accesor functions instead of direct access hrtimer: Make the hrtimer_cpu_base::hres_active field unconditional, to simplify the code hrtimer: Make room in 'struct hrtimer_cpu_base' ...

ALSA/dummy: Replace tasklet with softirq hrtimer

2018-01-16T08:51:22+00:00

The tasklet is used to defer the execution of snd_pcm_period_elapsed() to the softirq context. Using the HRTIMER_MODE_SOFT mode invokes the timer callback in softirq context as well which renders the tasklet useless.
