i.e. after registering the sound card the value changes/gets corrupted, and c3998f20 is not the value I get everytime, so I am thinking it is corrrupted somehow.

I'd guess the memory gets overwritten.

But back in probe, after above function are executed, i.e. after register codec is over, I get the correct value for eac->pcm->private_data i.e. c3d81180, but by now the value of pcm->private_data is corrupted!

This implies that eac->pcm != pcm.

It seems quite a lot of memory gets corrupted. Try to check which one of the various "eac" and "pcm" pointers changes its value.
