Subject: [PATCH RFC 0/5] Add devres support to card resources
Date: Thu, 13 Sep 2018 08:05:22 +0200 [thread overview]
Message-ID: <20180913060527.24694-1-tiwai@suse.de> (raw)
Hi,
the devres or device-managed resource allocation is a popular method
among many drivers but we didn't have such a mechanism for the core
sound card objects. Here is an attempt to implement that.
The first patch gives the devm-version of page allocator helper, and
the second patch provides the devm-version of snd_card_new().
The rest patches are examples of the new API usages.
As of now, this patch series is still an RFC. The usefulness of this
is still unclear, but I believe this can be used in all legacy ALSA
drivers pretty well. For ASoC, this would help very little,
supposedly, though.
The latest patches are found in topic/devres branch of my sound.git
tree, too.
thanks,
Takashi
