Subject: [PATCH AUTOSEL 4.9 08/13] hwmon: (ibmpowernv) Remove bogus __init annotations

From: Geert Uytterhoeven <geert@...ux-m68k.org>

[ Upstream commit e3e61f01d755188cb6c2dcf5a244b9c0937c258e ]

If gcc decides not to inline make_sensor_label():

    WARNING: vmlinux.o(.text+0x4df549c): Section mismatch in reference from the function .create_device_attrs() to the function .init.text:.make_sensor_label()
    The function .create_device_attrs() references
    the function __init .make_sensor_label().
    This is often because .create_device_attrs lacks a __init
    annotation or the annotation of .make_sensor_label is wrong.

As .probe() can be called after freeing of __init memory, all __init
annotiations in the driver are bogus, and should be removed.
