From e367305769d091bc8a0026d69136eb77fd055784 Mon Sep 17 00:00:00 2001 From: Matthias Schiffer Date: Wed, 27 Sep 2023 15:33:31 +0200 Subject: [PATCH] core: return FDT_ADDR_T_NONE from devfdt_get_addr_[size_]name() on errors Checking for the error cast to fdt_addr_t is rather awkward - IS_ERR() can be used, but it's not really made to be used on fdt_addr_t, which may not even be the same size as a native pointer. Most places in U-Boot only check for FDT_ADDR_T_NONE; let's adjust the error return to match the expectation.
