[PATCH 5/5] ASoC: sh: rz-ssi: Add functions to get/set substream pointer
by Lad Prabhakar 10 Jan '22

10 Jan '22

A copy of substream pointer is stored in priv structure during rz_ssi_dai_trigger() callback ie in SNDRV_PCM_TRIGGER_START case and the pointer is assigned to NULL in case of SNDRV_PCM_TRIGGER_STOP. The driver used the locks only in rz_ssi_stream_is_valid() and assigned the local substream pointer to NULL in rz_ssi_dai_trigger() callback and in rest of the driver no locking was used while assigning substream pointer. This patch adds functions to get/set substream pointer with locks acquired and replaces the instances of access to substream pointer with the get/set functions.

amixer: needs sget/cget support in stdin mode

alsa-project/alsa-utils issue #135 was opened from nick87720z: I used alsactl and amixer to implement highly effective volume control applet executor. At least it's able to keep pace at touchpad, which sends 1000 scroll events in only 18 to 12 seconds. `amixer --stdin` handles control events, while `alsactl monitor` is even source for applet display part (it's tint2 executor). But in order to get values to display - this display part has to run `alsactl sget` per request. Can't these commands be supported in stdin mode? From first look - expected lines number doesn't look unpredictable: for `sget` it depends on number of channels, and for `cget` - probably fixed. Even `controls` command also could be supported, since it lists channel from biggest ID to 1, so moment of numid=1 could be understood as end of list.
