What operation might be in progress here? Did you encounter some problems?
Please explain it in more detail in the commit message.

Ideally we should never reach this function with a pending operation. I
think we should do a proper wait in the place we did the operation that
needs waiting rather than here. That would make sure operations other
than shutdown, like reads, also work properly.


We have faced issue while doing nor flash read/write test with specific nor part.
Will check once again with the same part and post new patch.
