2022-11-10ASoC: stm32: i2s: remove irqf_oneshot flagOlivier Moysan1-1/+1
The IRQF_ONESHOT flag allows to ensure that the interrupt is not unmasked after the hard interrupt context handler has been executed and the thread has been woken. The interrupt line is unmasked after the thread handler function has been executed. The STM32 I2S driver does not implement a threaded IRQ handler. So, the IRQF_ONESHOT flag is not useful in I2S driver. Remove this flag to allow the interrupt routine to be managed as a thread in RT mode.

2022-09-27ASoC: stm: Fix PM disable depth imbalance in stm32_i2s_probeZhang Qilong1-2/+2
The pm_runtime_enable will increase power disable depth. Thus a pairing decrement is needed on the error handling path to keep it balanced according to context. We fix it by moving pm_runtime_enable to the endding of stm32_i2s_probe.

2022-06-27ASoC: stm32: Migrate to new style legacy DAI naming flagCharles Keepax1-0/+1
Change the legacy DAI naming flag from opting in to the new scheme (non_legacy_dai_naming), to opting out of it (legacy_dai_naming). These drivers appear to be on the CPU side of the DAI link and currently uses the legacy naming, so add the new flag.

The commit e894efef9ac7 ("ASoC: core: add support to card rebind") allows to rebind the sound card after a rebind of one of its component. With this commit, the sound card is actually rebound, but may be no more functional.

2019-08-02ASoC: Remove dev_err() usage after platform_get_irq()Stephen Boyd1-4/+1
We don't need dev_err() messages when platform_get_irq() fails now that platform_get_irq() prints an error message itself when something goes wrong. Let's remove these prints with a simple semantic patch. // <smpl> @@ expression ret; struct platform_device *E; @@ ret = ( platform_get_irq(E, ...) | platform_get_irq_byname(E, ...) ); if ( \( ret < 0 \| ret <= 0 \) ) { ( -if (ret != -EPROBE_DEFER) -{ ... -dev_err(...); -... } | ... -dev_err(...); ) ... } // </smpl> While we're here, remove braces on if statements that only have one statement (manually).
