Subject: [PATCH v2 2/4] media: Rearrange the fields in the G_TOPOLOGY IOCTL argument
Date: Mon, 22 Feb 2016 22:47:02 +0200 [thread overview]
Message-ID: <1456174024-11389-3-git-send-email-sakari.ailus@linux.intel.com> (raw)
In-Reply-To: <1456174024-11389-1-git-send-email-sakari.ailus@linux.intel.com>
From: Sakari Ailus <sakari.ailus@iki.fi>
This avoids having multiple reserved fields in the struct. Reserved fields
are added in order to align the struct size to a power of two as well.
