[Mark Brown]

The patch

   ASoC: core: use list_del_init and move it back to soc_cleanup_component

has been applied to the asoc tree at

   https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git for-5.4

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

Subject: [PATCH] ASoC: core: use list_del_init and move it back to
 soc_cleanup_component

commit a0a4bf57a977 ("ASoC: core: delete component->card_list in soc_remove_component only")
was trying to fix a kernel oops when list_del was called twice without
re-init the list. Use list_del_init() can solve it, too. Besides, it
will be more readable if we cleanup all component related resource at
soc_cleanup_component().
