Subject: [PATCH v2 10/16] ASoC: fsl-ssi: reorder and document fsl_ssi_private
Date: Sat, 15 Mar 2014 13:44:18 +0100	[thread overview]
Message-ID: <1394887464-969-11-git-send-email-mpa@pengutronix.de> (raw)
In-Reply-To: <1394887464-969-1-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.
