Subject: regmap module_put usage.
Date: Mon, 05 Sep 2011 13:55:15 +0100	[thread overview]
Message-ID: <4E64C6B3.80105@cam.ac.uk> (raw)

Hi Mark,

I'm playing around with converting an IIO driver over to regmap
(to get a feel for when it makes sense and when it doesn't).

Right now, calling regmap_exit() results in a module_put of the
regmap-spi module which never has a module_get and hence it's
module use count wraps around and all hell breaks loose?

Am I missing something about where that get should occur?

It's entirely plausible I just have a local bug but I right
now I can't see how the logic is supposed to function!

Thanks,

Jonathan
