Hi Stephen,

My fault, I've been too lazy with that commit for too long, and code like
writel(!reg1 | reg2, adr) is error prone. Artem did point out the warning
already, so that's on me.

I'll mend the fix in a V2 to a cleanup patch already submitted to linux-mtd.

Cheers.

PS: there will be another warning about an unused function
doc_get_erase_count(). This one will be fixed a bit later I'm afraid.
