From c3028b951ed15b7c3409c6d9a69dad615de23d3f Mon Sep 17 00:00:00 2001 From: Nicolas Saenz Julienne Date: Fri, 31 Jul 2020 12:02:48 +0200 Subject: of: address: Fix parser address/size cells initialization bus->count_cells() parses cells starting from the node's parent. This is not good enough for parser_init() which is generally parsing a bus node. Revert to previous behavior using of_bus_n_*_cells().
