Would the above make readers of that code wonder whether read_poll_timeout()
perhaps returns a boolean? Wouldn't it be better to test the
read_poll_timeout() return value as follows?

  	return read_poll_timeout(ufshcd_readl, val, val & UIC_COMMAND_READY,
  				  500, UIC_CMD_TIMEOUT * 1000, false, hba,
  				  REG_CONTROLLER_STATUS) == 0;

Thanks,

Bart.
