At least gcc version 4.3.5 (Debian 4.3.5-4) shows them. What's
the compiler you have?

Yes let's do that rather than start copying things around. I'll apply
the following fix to the omap-for-v3.9/twl branch.

Subject: [PATCH] ARM: OMAP2+: Fix twl section warnings related to omap_twl4030_audio_init
With the recent twl related changes we can now get:
WARNING: arch/arm/mach-omap2/built-in.o(.text+0x15f88): Section mismatch in
reference from the function sdp3430_twl_gpio_setup() to the function
.init.text:omap_twl4030_audio_init()
The function sdp3430_twl_gpio_setup() references
the function __init omap_twl4030_audio_init().
This is often because sdp3430_twl_gpio_setup lacks a __init
annotation or the annotation of omap_twl4030_audio_init is wrong.
WARNING: arch/arm/mach-omap2/built-in.o(.text+0x16968): Section mismatch in
reference from the function zoom_twl_gpio_setup() to the function
.init.text:omap_twl4030_audio_init()
The function zoom_twl_gpio_setup() references
the function __init omap_twl4030_audio_init().
This is often because zoom_twl_gpio_setup lacks a __init
annotation or the annotation of omap_twl4030_audio_init is wrong.
Fix this by removing __init from omap_twl4030_audio_init() as
suggested by Peter Ujfalusi <peter.ujfalusi@ti•com>.
