    ARM: OMAP4: hsmmc: check for null pointer · 1ee47b0a
    Balaji T K authored
    platform_device pdev can be NULL if CONFIG_MMC_OMAP_HS is not set.
    Add check for NULL pointer. while at it move the duplicated functions
    to omap4-common.c
    
    Fixes the following boot crash seen with omap4sdp and omap4panda
    when MMC is disabled.
    
    Unable to handle kernel NULL pointer dereference at virtual address 0000008c
    pgd = c0004000
    [0000008c] *pgd=00000000
    Internal error: Oops: 5 [#1] SMP ARM
