Subject: [PATCH 03/27] mtd: nand: update examples in the documentation to use mtd_to_nand()
Date: Mon, 16 Nov 2015 14:37:36 +0100	[thread overview]
Message-ID: <1447681080-31232-4-git-send-email-boris.brezillon@free-electrons.com> (raw)
In-Reply-To: <1447681080-31232-1-git-send-email-boris.brezillon@free-electrons.com>

mtd_to_nand() has been introduced to hide accesses to mtd->priv.
All NAND controller drivers should use it instead of directly accessing
the ->priv field.
