4.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Arnd Bergmann arnd@arndb.de
commit 9505b98ccddc454008ca7efff90044e3e857c827 upstream.
pxa_cpufreq_init_voltages() is marked __init but usually inlined into the non-__init pxa_cpufreq_init() function. When building with clang, it can stay as a standalone function in a discarded section, and produce this warning:
WARNING: vmlinux.o(.text+0x616a00): Section mismatch in reference from the function pxa_cpufreq_init() to the function .init.text:pxa_cpufreq_init_voltages() The function pxa_cpufreq_init() references the function __init pxa_cpufreq_init_voltages(). This is often because pxa_cpufreq_init lacks a __init annotation or the annotation of pxa_cpufreq_init_voltages is wrong.
