[PATCH 4.9 071/118] cpufreq: pxa2xx: remove incorrect __init annotation

From: Greg Kroah-Hartman
Date: Fri Mar 22 2019 - 09:01:19 EST

4.9-stable review patch. If anyone has any objections, please let me know.


From: Arnd Bergmann <arnd@xxxxxxxx>

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.
