TBH, the current state of dumping UFSHC registers itself is just annoying as it
pollutes the kernel ring buffer. I don't think any peripheral driver in the
kernel does this. Please dump only relevant registers, not everything that you
feel like dumping.

I wouldn't mind if the code for dumping  UFSHC registers would be removed.

Instead of removing, I'm planning to move the dump to dev_coredump framework.
But should we move all the error prints also? Like all ufshcd_print_*()
functions?

Hmm ... we may be better off to check which of these functions can be removed rather than moving all of them to another framework.

Thanks,

Bart.
