[PATCH v3 1/4] ASoC: cs35l45: Checks index of cs35l45_irqs[]
From: Ricardo Rivera-Matos rriveram@opensource.cirrus.com
Checks the index computed by the virq offset before printing the error condition in cs35l45_spk_safe_err() handler.

Adds "Analog PCM Volume" control with supported values 0 = 10dB,1 = 13dB,2 = 16dB and 3 = 19dB. The amplifier can operate either in Speaker Mode or Receiver Mode as configured by the user. Speaker Mode has four gain options to support maximum amplifier output amplitude for loud speaker application. Receiver Mode has further optimized noise performance while maintaining sufficient output to support phone receiver application. While configured in Receiver Mode, the analog PCM Volume control is disabled and the analog gain is fixed to 1dB.

The "AMP Enable Switch" is useful in systems with multiple amplifiers connected to the same audio bus but not all of them are needed for all use cases.
This doesn't apply against current code, please check and resend.

I am happy enough for this to be merged, since it clearly does no harm. So:

But I do still have a slight reservation of what is the point of this error check? This handler is static and can only be called from within cs35l45.c and the only code that registers IRQs goes through the cs35l45_irqs array and registers IRQs from there, so how does this ever end up with i being out of bounds?
And whilst I would not add this to this patch. I do also think perhaps Ricardo had a point in his email, the IRQ handler should probably be renamed, since it handles more than just the spk_safe_err's, perhaps something like cs35l45_report_err. On why the watchdog and global error call this as well, that was a review comment on an earlier patch since the handlers for those errors only printed a message, they might as well be combined with the spk_safe error that also only printed a message. If at some point separate handling is added for them they can be split out.
Thanks, Charles

Thanks Charles, I had missed that comment. It’s clear to me now.

All being well this means that it will be integrated into the linux-next tree (usually sometime in the next 24 hours) and sent to Linus during the next merge window (or sooner if it is a bug fix), however if problems are discovered then the patch may be dropped or reverted.
You may get further e-mails resulting from automated or manual testing and review of the tree, please engage with people reporting problems and send followup patches addressing any issues that are reported if needed.
If any updates are required or you are submitting further changes they should be sent as incremental updates against current git, existing patches will not be replaced.
Please add any relevant lists and maintainers to the CCs when replying to this mail.
Thanks, Mark
