Subject: mmc: davinci: Make SDIO irq truly optional
X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=de2067448d0ece6b774026cc05dcb6d4ebfd1e1a;p=linux.git

mmc: davinci: Make SDIO irq truly optional

The following error is printed on Logic PD's DA850 EVM:
  davinci_mmc 1c40000.mmc: error -ENXIO: IRQ index 1 not found

Depending on the board, the SDIO interrupt may not be present, so use
the correct function to reflect that and prevent logging an error.
