If the device does not exist, of_get_child_by_name() will return NULL pointer. And devm_snd_soc_register_component() does not check it. Also, I have noticed that cpcap_codec_driver has not been used yet. Therefore, it should be better to check it in order to avoid the future dereference of the NULL pointer.

Thanks!
[1/1] ASoC: cpcap: Check for NULL pointer after calling of_get_child_by_name commit: f7a6021aaf02088870559f82fc13c58cda7fea1a
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
