Does regzbot track issues in linux-next?

They're not really regressions because they're not in a release yet.

Anyway I don't see where bdb616479eff419 comes from.

The issue was introduced by:

  701d2054fa31 fbdev: Make support for userspace interfaces configurable

The driver seems to only use info->dev in that one dev_info() line,
which seems purely cosmetic, so I think it could just be removed, eg:

diff --git a/drivers/video/fbdev/ps3fb.c b/drivers/video/fbdev/ps3fb.c
index d4abcf8aff75..a304a39d712b 100644
--- a/drivers/video/fbdev/ps3fb.c
+++ b/drivers/video/fbdev/ps3fb.c

-		 dev_driver_string(info->dev), dev_name(info->dev),

cheers
