[PATCH 5.1 17/54] ARM: omap2: remove incorrect __init annotation

From: Greg Kroah-Hartman
Date: Wed Jul 17 2019 - 23:04:28 EST

[ Upstream commit 27e23d8975270df6999f8b5b3156fc0c04927451 ]

omap3xxx_prm_enable_io_wakeup() is marked __init, but its caller is not, so
we get a warning with clang-8:

WARNING: vmlinux.o(.text+0x343c8): Section mismatch in reference from the function omap3xxx_prm_late_init() to the function .init.text:omap3xxx_prm_enable_io_wakeup()
The function omap3xxx_prm_late_init() references
the function __init omap3xxx_prm_enable_io_wakeup().
This is often because omap3xxx_prm_late_init lacks a __init
annotation or the annotation of omap3xxx_prm_enable_io_wakeup is wrong.

When building with gcc, omap3xxx_prm_enable_io_wakeup() is always
inlined, so we never noticed in the past.
