4.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Robert Jarzmik <robert.jarzmik@free.fr>
commit 41c89159a6ae5472d39ed8bded5b3b4e07a37944 upstream.
The commit fixing the conversion of pxamci to slot-gpio API fixed the inverted the logic of the read-only gpio. Unfortunately, the commit was tested on a non-inverted gpio, and not on the inverted one. And the fix did work partially, by luck.
This is the remaining missing part of the fix, trivial but still necessary.
