  checkpatch.pl warned:
WARNING: ENOSYS means 'invalid syscall nr' and nothing else
Align the return value to regcache_drop_region().

This warning popped up while initially returning ENOSYS in patch 1.

But I'm wondering if returning 0 for regcache_write is correct or not.
This might be a follow-up patch though.
