From 7a7a55afe7ba3a582658c9ef33b1cb479f18e68e Mon Sep 17 00:00:00 2001 From: Srinivas Kandagatla Date: Wed, 23 Mar 2016 16:43:36 +0000 Subject: [PATCH] libahci: save port map for forced port map 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.
