From 0b104773b4f72ccd8af98a2f1efe69b174c344d3 Mon Sep 17 00:00:00 2001 From: Rob Herring Date: Thu, 9 Apr 2020 17:49:21 -0600 Subject: PCI: Constify struct pci_ecam_ops struct pci_ecam_ops is typically DT match table data which is defined to be const. It's also best practice for ops structs to be const. Ideally, we'd make struct pci_ops const as well, but that becomes pretty invasive, so for now we just cast it where needed.
