Cover letter [PATCH 0/3] omap hsmmc init cleanup and section warning fixes for v3.4 merge window

Can you test something with these patches?

1. Build the gpio-twl4030.c as a module, but with HSMMC support built in
2. Boot on the 4430SDP

twl4030 gpio is used for card detect on OMAP3, so I tried this on my Beagle instead of 4430SDP.
The kernel boots up but does not detect/enumerate the mmc card.

3. Load the gpio-twl4030 module

I was expecting this to now detect the card, but I instead got this error which seems to tell gpio-twl4030 has problems when built/used as a module, outside of the mmc issues.

Looks like I was mislead with the errors and though the twl4030 gpio probe was bailing out with errors, which its not. It does seem to go ahead, does a mmc late init which registers the mmc omap_device and hence does a platform_device_add, but the device never seem to get probed. mmc driver is built in and registered.

4. Remove the gpio-twl4030 module
5. Re-load the gpio-twl4030.ko module

and report back what you get. Thanks.
