In the workaround added with 'commit b6f44082d5cd ("mmc: zynq_sdhci: Wait till sd card detect state is stable")' the timeout variable has post decrement. Whenever timeout happens, this post decrement is making timeout=0xffffffff, so timeout error print and return statement are never reached. Fix it by decrementing it inside the while loop.
