Some of MMC controllers (in my case msm_sdcc) can process automatically "busy line" and fire interrupt with "prog done" bit asserted, so we can use handler of this irq to turn off "doing bkops" flag. Otherwise it is possible to read mmc controller status and check busy line, in case it is already released we can skip HPI command.
