Subject: [PATCH v3 17/18] ASoC: fsl-ssi: reorder and document fsl_ssi_private
Date: Mon, 14 Apr 2014 15:35:47 +0200 [thread overview]
Message-ID: <1397482548-28463-18-git-send-email-mpa@pengutronix.de> (raw)
In-Reply-To: <1397482548-28463-1-git-send-email-mpa@pengutronix.de>
Reorder all variables in struct fsl_ssi_private to have groups that make
sense together. The patch also updates the struct documentation.
