From: Bean Huo <beanhuo@micron.com>
Occasionally, user-land applications initiate longer timeout values for certain commands through ioctl() system call. But so far we are still using a fixed timeout of 10 seconds in mmc_poll_for_busy() on the ioctl() path, even if a custom timeout is specified in the userspace application. This patch allows custom timeout values to override this default timeout values on the ioctl path.
