Subject: [PATCH 3/3] spi: allow registering empty spi_board_info lists
Date: Mon, 27 Feb 2017 20:08:48 -0800 [thread overview]
Message-ID: <20170228040848.9447-3-dmitry.torokhov@gmail.com> (raw)
In-Reply-To: <20170228040848.9447-1-dmitry.torokhov@gmail.com>
Many boards form list of spi_board_info entries depending on config,
and it is possible to end up with empty list. Do not report error
in such cases.
