commit bfd694d5e2 ("mmc: core: Add tunable delay
before detecting card after card is inserted") adds
"u32 cd_debounce_delay_ms" to the last of mmc_gpio
struct and cause "char cd_label[0]" NOT work as string
pointer of card detect label, when "cat /proc/interrupts",
the devname for card detect gpio is incorrect as below:
144: 0 gpio-mxc 22 Edge ▒
161: 0 gpio-mxc 7 Edge ▒
Move the cd_label field down to fix this, and drop the
zero from the array size to prevent future similar bugs,
the result is correct as below:
144: 0 gpio-mxc 22 Edge 2198000.mmc cd
161: 0 gpio-mxc 7 Edge 2190000.mmc cd
