From 96c623e51f1c40bf524decc48c6fac7ce5dd41f7 Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Mon, 6 Nov 2017 14:26:10 +0100 Subject: of: add of_property_read_variable_* dummy helpers Commit a67e9472da42 ("of: Add array read functions with min/max size limits") added a new interface for reading variable-length arrays from DT properties. One user was added in dsa recently and this causes a build error because that code can be built with CONFIG_OF disabled: net/dsa/dsa2.c: In function 'dsa_switch_parse_member_of': net/dsa/dsa2.c:678:7: error: implicit declaration of function 'of_property_read_variable_u32_array'; did you mean 'of_property_read_u32_array'? [-Werror=implicit-function-declaration] This adds a dummy functions for of_property_read_variable_u32_array() and a few others that had been missing here. I decided to move of_property_read_string() and of_property_read_string_helper() in the process to make it easier to compare the two sets of function prototypes to make sure they match.
