Re: [PATCH 1/4] ASoC: soc-dapm.c: don't use kzalloc() for param on snd_soc_dai_link_event_pre_pmu()

Hi Mark

...

Current snd_soc_dai_link_event_pre_pmu() is using kzalloc() / kfree() for "params", but it is fixed size, and not used on private data. It is used for setup rtd at end of this function, just a local variable. We don't need to use kzalloc() / kfree() for it. This patch replace it as local variable.

The reason we're allocating it dynamically is that it's quite large (608 bytes on arm64) and is starting to get a bit excessive for allocation on the stack, especially when you're building with some of the KASAN type stuff that increases stack usage.

Oh, I see. Thank you for clearing the reason. I think it is very nice to have such comment on the code.

Thank you for your help !!
