From bfc1c6b4838501d10aa48c0e92eaf70976f4b2dd Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Tue, 4 Jul 2017 13:31:22 -0600 Subject: [PATCH] dm: ahci: Correct uclass private data This is expected to be attached to the uclass and the code operates that way, but the uclass has not been updated. Fix it to avoid using memory at address 0.
