From 58e71097ced49600de1b38d2b59a823a9db66f19 Mon Sep 17 00:00:00 2001 From: Eric Auger Date: Fri, 19 Feb 2016 09:42:30 -0700 Subject: device_tree: qemu_fdt_getprop_cell converted to use the error API This patch aligns the prototype with qemu_fdt_getprop. The caller can choose whether the function self-asserts on error (passing &error_fatal as Error ** argument, corresponding to the legacy behavior), or behaves differently such as simply output a message. In this later case the caller can use the new lenp parameter to interpret the error if any.
