Subject: [EXT] Re: [PATCH] i2c: imx: Defer probing if EDMA not available

Caution: EXT Email

Hello,

EDMA may be not available or defered due to dependencies on other
modules, If these scenarios is encountered, we should defer probing.

I'd write:

       i2c: imx: Defer probing if requesting DMA yields EPROBE_DEFER

       DMA might not be available yet when the i2c device probes.
       Properly handle EPROBE_DEFER on dma channel allocation by
       passing on this error.

It would be nice to point out where/how this failed for you.

Other than that this looks reasonable.

Hi, Uwe,

Thanks very much for your comments, That looks good.

Best Regards,
Peng

Best regards
Uwe
