[PATCH net-next 5/8] net: dsa: felix: remove confusing/incorrect comment from felix_setup()
Posted by Vladimir Oltean 2 years, 10 months ago
That comment was written prior to knowing that what I was actually
seeing was a manifestation of the bug fixed in commit b4024c9e5c57
("felix: Fix initialization of ioremap resources").

There isn't any particular reason now why the hardware initialization is
done in felix_setup(), so just delete that comment to avoid spreading
misinformation.
