Subject: [PATCH 07/62] UBI: Extend UBI layer debug/messaging capabilities
Date: Mon, 23 May 2016 10:25:55 +0200	[thread overview]
Message-ID: <1463992010-31537-8-git-send-email-t.remmet@phytec.de> (raw)
In-Reply-To: <1463992010-31537-1-git-send-email-t.remmet@phytec.de>

From: Tanya Brokhman <tlinder@codeaurora.org>

If there is more then one UBI device mounted, there is no way to
distinguish between messages from different UBI devices.
Add device number to all ubi layer message types.

The R/O block driver messages were replaced by pr_* since
ubi_device structure is not used by it.

Amended a bit by Artem.
