From 47c0f3692d27702cb11f67fe05b71b98d77d007c Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Sat, 29 Jul 2017 11:35:06 -0600 Subject: [PATCH] dm: sata: dw_sata: Pass uc_priv to internal functions With driver model sata_dev_desc[] does not exist. We still want to use the common code of this driver so update it to pass struct ahci_uc_priv * to each of these functions, instead of an integer which must be looked up in sata_dev_desc[].
