From c10b26abeb53cabc1e6271a167d3f3d396ce0218 Mon Sep 17 00:00:00 2001 From: Nathan Chancellor Date: Wed, 17 Oct 2018 17:52:07 -0700 Subject: [PATCH 1/3] ARM: OMAP2+: hwmod: Fix some section annotations When building the kernel with Clang, the following section mismatch warnings appears: WARNING: vmlinux.o(.text+0x2d398): Section mismatch in reference from the function _setup() to the function .init.text:_setup_iclk_autoidle() The function _setup() references the function __init _setup_iclk_autoidle(). This is often because _setup lacks a __init annotation or the annotation of _setup_iclk_autoidle is wrong. WARNING: vmlinux.o(.text+0x2d3a0): Section mismatch in reference from the function _setup() to the function .init.text:_setup_reset() The function _setup() references the function __init _setup_reset(). This is often because _setup lacks a __init annotation or the annotation of _setup_reset is wrong. WARNING: vmlinux.o(.text+0x2d408): Section mismatch in reference from the function _setup() to the function .init.text:_setup_postsetup() The function _setup() references the function __init _setup_postsetup(). This is often because _setup lacks a __init annotation or the annotation of _setup_postsetup is wrong. _setup is used in omap_hwmod_allocate_module, which isn't marked __init and looks like it shouldn't be, meaning to fix these warnings, those functions must be moved out of the init section, which this patch does.
