Subject: [PATCH] hwmon: (ibmpowernv) Remove bogus __init annotations
Date: Sun, 28 Oct 2018 18:16:51 +0100	[thread overview]
Message-ID: <20181028171651.30751-1-geert@linux-m68k.org> (raw)

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.
