Looks fine to me.

Though card didn't support HPI,someone could use the send_hpi_cmd().
Then maybe didn't work fine.
Because card->ext_csd.hpi_cmd didn't set.
So if card didn't support hpi, return the waring message.
And CMD12's flags is MMC_RSP_R1B.

For small size non-dma sdio transactions, it is sometimes better to poll
the mmc host and avoid interrupts altogether. Polling lowers the number
of interrupts and context switches. Tests have shown that for small
transactions, only a few polling iterations are needed, so this is worth
while.

The davinci mmc interrupt handler fills the fifo, as long as the DXRDY
or DRRDY bits are set in the status register.
If interrupts fire during this loop, they will be handled by the
handler, but the interrupt controller will still buffer these. As a
result, the handler will be called again to serv
