Subject: [PATCH 7/7] pstore/ram_core: Get rid of prz->ecc enable/disable flag
Date: Mon, 18 Jun 2012 19:15:56 -0700	[thread overview]
Message-ID: <1340072156-6225-7-git-send-email-anton.vorontsov@linaro.org> (raw)
In-Reply-To: <20120619021050.GA19387@lizard>

Nowadays we can use prz->ecc_size as a flag, no need for the special
member in the prz struct.
