Subject: [PATCH 4/5] backports: remove regulator drivers
From: Hauke Mehrtens <hauke () hauke-m ! de>
Date: 2014-09-06 19:44:18
Message-ID: 1410032659-30404-5-git-send-email-hauke () hauke-m ! de

It looks like no one is using the regulator drivers and maintaining
them costs some time because they often break. When someone needs
a specific driver please send a patch adding this one specific driver,
maintaining a small subset is not a problem, but maintaining all is a
big task.
