From 56134e3c649b97085df50fe85ae479e3d3a87d7f Mon Sep 17 00:00:00 2001 From: Sergei Shtylyov Date: Sun, 23 Jul 2017 22:41:45 +0300 Subject: [PATCH] of_pci: use of_property_read_u32() of_get_pci_domain_nr() somehow didn't use of_property_read_u32() though it was long available, basically open-coding it. Using the modern DT API saves several LoCs/bytes and also adds some prop sanity checks as a bonus...
