--------------------------------

[ Upstream commit e3f0c638 ]

On remove, we get an error for "Runtime PM usage count underflow!". I guess
this driver is mostly built-in, and this issue has gone unnoticed for a
while. Somehow I did not catch this issue with my earlier fix done with
commit 4e0f5cc6 ("serial: 8250_omap: Fix probe and remove for PM
runtime").
