From: Simon Glass Date: Thu, 15 Jun 2017 03:28:32 +0000 (-0600) Subject: dm: ahci: Rename struct ahci_probe_ent X-Git-Tag: v2017.09-rc1~214^2~62 X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=2c9f9efb3d43568e5e5843c600e8bfc2d42ac23e;p=oweals%2Fu-boot.git dm: ahci: Rename struct ahci_probe_ent This is not a very useful name since once it is probed it still hangs around. With driver model we will use uclass data for this, so rename the struct.
