> WARNING: arch/arm/mach-omap2/built-in.o(.text+0xd0f0): Section mismatch in reference from the function sdp3430_twl_gpio_setup() to the function .init.text:omap2_hsmmc_init()
> The function sdp3430_twl_gpio_setup() references
> the function __init omap2_hsmmc_init().
> This is often because sdp3430_twl_gpio_setup lacks a __init

> 
> sdp3430_twl_gpio_setup() is called via platform data from the
> gpio-twl4030 module, which can be inserted and removed at runtime.
> This makes sdp3430_twl_gpio_setup() callable at runtime, and prevents
> it being marked with an __init annotation.
> 
> As it calls omap2_hsmmc_init() unconditionally, the only resolution to
> this warning is to remove the __init markings from omap2_hsmmc_init()
> and its called functions.  This addresses the functions in hsmmc.c.

We'll try to sort this out also properly for v3.4, meanwhile:
