Subject: [PATCH mvebu + mvebu/dt64 2/4] firmware: turris-mox-rwtm: report failures better
Date: Mon,  8 Mar 2021 16:37:01 +0100	[thread overview]
Message-ID: <20210308153703.23097-2-kabel@kernel.org> (raw)
In-Reply-To: <20210308153703.23097-1-kabel@kernel.org>

Report a notice level message if a command is not supported by the rWTM
firmware.

This should not be an error, merely a notice, because the firmware can
be used on non-CZ.NIC boards that do not have manufacturing information
burned.

Signed-off-by: Marek Behún <kabel@kernel.org>
Fixes: 389711b37493 ("firmware: Add Turris Mox rWTM firmware driver")
