Hi Varka,

   Regarding a point you suggested.

Hmm.. fsl_asrc_ids is called in probe(), so it's probably not a good choice
to put them after probe/remove. And actually not every driver does so.
For example drivers/i2c/busses/i2c-s3c2410.c

I think it should be okay to put here if it contains data.

Thank you,
Nicolin
