Subject: [alsa-devel] Applied "ASoC: soc-core: merge soc_free_pcm_runtime() and soc_rtd_free()" to the asoc tree
Date: Tue,  1 Oct 2019 12:40:48 +0100 (BST)
Message-ID: <20191001114048.E624927429C0@ypsilon.sirena.org.uk> (raw)
In-Reply-To: <878squf7oi.wl-kuninori.morimoto.gx@renesas.com>

The patch

   ASoC: soc-core: merge soc_free_pcm_runtime() and soc_rtd_free()

has been applied to the asoc tree at

   https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git for-5.5

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: soc-core: merge soc_free_pcm_runtime() and
 soc_rtd_free()

"rtd"      is handled by soc_xxx_pcm_runtime(), and
"rtd->dev" is handled by soc_rtd_xxx().

There is no reason to separate these, and it makes code complex.
We can free these in the same time.

Here soc_rtd_free() (A) which frees rtd->dev is called from
soc_remove_link_dais() many times (1).
Then, it is using dev_registered flags to avoid multi kfree() (2).
This is no longer needed if we can merge these functions.

	static void soc_remove_link_dais(...)
	{
		...
(1)		for_each_comp_order(order) {
(1)			for_each_card_rtds(card, rtd) {

(A)				soc_rtd_free(rtd);
				...
			}
		}
	}

(A)	static void soc_rtd_free(...)
	{
(2)		if (rtd->dev_registered) {
			/* we don't need to call kfree() for rtd->dev */
			device_unregister(rtd->dev);
(2)			rtd->dev_registered = 0;
		}
	}

This patch merges soc_rtd_free() into soc_free_pcm_runtime().
