Yeah, the previous dev_err was actually copy-pasted from a similar
function that already existed.  When I rebased to l2-mtd/spinor, I did
the same copy-paste but that branch has pr_err instead of dev_err.
I'm a noob, so I didn't want to change things without a good
explanation :)  On the other hand, I'm in favor of using dev_err
instead.

Same here as above, copy-pasted, and so the logic is what already
existed.  I double-checked the calling code, and like you say, the
callers do not tell the situations apart.  About half the calls assume
any error is timeout.  The others either pass return value or some
other error up, or they ignore it.

Thanks,
Graham
