From: Arnd Bergmann <arnd@xxxxxxxx> [ 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.
