           Summary: linux-2.6/arch/arm/mach-omap2/mmc-twl4030.c:400: Memory
                    leak: mmc
           Product: Platform Specific/Hardware
           Version: 2.5
     KernelVersion: latest git tree
          Platform: All
        OS/Version: Linux
              Tree: Mainline
            Status: NEW
          Severity: normal
          Priority: P1
         Component: ARM
        AssignedTo: linux-arm-kernel at lists.arm.linux.org.uk
        ReportedBy: danielm77 at spray.se


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
