Building with clang finds a mistaken __init tag:

WARNING: vmlinux.o(.text+0x5e4250): Section mismatch in reference from the function davinci_mmcsd_probe() to the function .init.text:init_mmcsd_host()
The function davinci_mmcsd_probe() references
the function __init init_mmcsd_host().
This is often because davinci_mmcsd_probe lacks a __init
annotation or the annotation of init_mmcsd_host is wrong.
