[alsa-devel] [PATCH v2 0/5] ASoC: twl6040: Updates for 3.9
Hi Mark, Liam,
Changes since v1: - patch 2 for twl6040_resume() has been replaced with a simpler one
Cover letter from v1:
Small fixe from Misael for twl6040 codec driver and devm_* conversion, switch to system workqueue and dead code removal.
Regards, Peter --- Misael Lopez Cruz (1): ASoC: twl6040: Convert PLUGINT to no-suspend irq
Peter Ujfalusi (4): ASoC: twl6040: Only set the bias_level once in twl6040_resume() ASoC: twl6040: Convert to use devm_* when possible ASoC: twl6040: Switch to use system workqueue for jack reporting ASoC: twl6040: Remove leftover code from hs/hf ramp implementation

Convert headset PLUGINT interrupt to NO_SUSPEND type in order to allow handling of insertion/removal events while device is suspended.

No need to set the bias_level twice to _STANDBY - since this is the only state the device could be at suspend time. The driver do not support idle_bias_off yet.

In this way we can clean up the probe and remove paths

There's no need to create a queue for this anymore

The code to do the ramp has been removed a long time ago. Remove the remaining code as well since this is not needed.
