Message-Id: <1440061956-29064-6-git-send-email-mpa@pengutronix.de> Date: Thu, 20 Aug 2015 11:12:36 +0200 From: Markus Pargmann <mpa@...gutronix.de> To: Mark Brown <broonie@...nel.org> Cc: linux-kernel@...r.kernel.org, linux-arm-kernel@...ts.infradead.org, kernel@...gutronix.de, Irina Tirdea <irina.tirdea@...el.com>, Markus Pargmann <mpa@...gutronix.de> Subject: [PATCH v2 5/5] regmap: No multi_write support if bus->write does not exist There is no multi_write support available if we cannot use raw_write. This is the case if bus->write is not implemented. This patch adds a condition that we need bus and bus->write so that can_multi_write is true.
