In the function twl4030_mmc_init the mmc is allocated in a loop.

In the loop there is a switch where the default case looks like this:

		default:
			pr_err("MMC%d configuration not supported!\n", c->mmc);
			continue;

When that path is used the mmc will leak memory. I suggest adding a kfree there.

This leak was found by cppcheck - http://sourceforge.net/projects/cppcheck
