From mboxrd@z Thu Jan 1 00:00:00 1970 From: srinivas.kandagatla@linaro.org (Srinivas Kandagatla) Date: Fri, 1 Apr 2016 08:52:56 +0100 Subject: [PATCH v3 1/3] libahci: save port map for forced port map In-Reply-To: <1459497178-31090-1-git-send-email-srinivas.kandagatla@linaro.org> References: <1459497178-31090-1-git-send-email-srinivas.kandagatla@linaro.org> Message-ID: <1459497178-31090-2-git-send-email-srinivas.kandagatla@linaro.org> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org In usecases where force_port_map is used saved_port_map is never set, resulting in not programming the PORTS_IMPL register as part of initial config. This patch fixes this by setting it to port_map even in case where force_port_map is used, making it more inline with other parts of the code.
