The tasklet is an old API that should be deprecated, usually can be converted to another decent API. In UA101 driver, a tasklet is still used for handling the output URBs. It can be achieved gracefully with a work queued in the high-prio system workqueue, too. This patch replaces the tasklet usage in UA101 driver with a simple work.

The tasklet is an old API that should be deprecated, usually can be converted to another decent API. In ALSA core timer API, the callbacks can be offlined to a tasklet when a flag is set in the timer backend. It can be achieved gracefully with a work queued in the high-prio system workqueue. This patch replaces the usage of tasklet in ALSA timer API with a simple work. Currently the tasklet feature is used only in the system timer and hrtimer backends, so both are patched to use the new flag name SNDRV_TIMER_HW_WORK, too.

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 96c7d478 "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.

The Mic connects to the Nid 0x19, but the configuration of Nid 0x19 is not defined to Mic, and also need to set the coeff to enable the auto detection on the Nid 0x19. After this change, the Mic plugging in or plugging out could be detected and could record the sound from the Mic. And the coeff value is suggested by Kailang of Realtek.

There've been quite a few regression reports about the lowered volume (reduced to ca 65% from the previous level) on Lenovo Thinkpad X1 after the commit d2cd795c ("ALSA: hda - fixup for the bass speaker on Lenovo Carbon X1 7th gen"). Although the commit itself does the right thing from HD-audio POV in order to have a volume control for bass speakers, it seems that the machine has some secret recipe under the hood. Through experiments, Benjamin Poirier found out that the following routing gives the best result: * DAC1 (NID 0x02) -> Speaker pin (NID 0x14) * DAC2 (NID 0x03) -> Shared by both Bass Speaker pin (NID 0x17) & Headphone pin (0x21) * DAC3 (NID 0x06) -> Unused DAC1 seems to have some equalizer internally applied, and you'd get again the output in a bad quality if you connect this to the headphone pin. Hence the headphone is connected to DAC2, which is now shared with the bass speaker pin. DAC3 has no volume amp, hence it's not connected at all. For achieving the routing above, this patch introduced a couple of workarounds: * The connection list of bass speaker pin (NID 0x17) is reduced not to include DAC3 (NID 0x06) * Pass preferred_pairs array to specify the fixed connection Here, both workarounds are needed because the generic parser prefers the individual DAC assignment over others. When the routing above is applied, the generic parser creates the two volume controls "Front" and "Bass Speaker". Since we have only two DACs for three output pins, those are not fully controlling each output individually, and it would confuse PulseAudio. For avoiding the pitfall, in this patch, we rename those volume controls to some unique ones ("DAC1" and "DAC2"). Then PulseAudio ignore them and concentrate only on the still good-working "Master" volume control. If a user still wants to control each DAC volume, they can still change manually via "DAC1" and "DAC2" volume controls.

On SKL+ Intel platforms, the driver selection is handled by the snd_intel_dspcfg, and when the HDaudio legacy driver is not selected, be it with the auto-selection or user preferences with a kernel parameter, the probe aborts with no logs, only a -ENODEV return value. Having no dmesg trace, even with dynamic debug enabled, makes support more complicated than it needs to be, and even experienced users can be fooled. A simple dev_dbg() trace solves this problem.

In snd_hdac_device_init pm_runtime_set_active is called to increase child_count in parent device. But when it is failed to build connection with GPU for one case that integrated graphic gpu is disabled, snd_hdac_ext_bus_device_exit will be invoked to clean up a HD-audio extended codec base device. At this time the child_count of parent is not decreased, which makes parent device can't get suspended. This patch calls pm_runtime_set_suspended to decrease child_count in parent device in snd_hdac_device_exit to match with snd_hdac_device_init. pm_runtime_set_suspended can make sure that it will not decrease child_count if the device is already suspended.
