commit cef456cd354ef485f12d57000c455e83e416a2b6 upstream.
As nice as it would be to update firmware faster, that patch broke at least two different boards, an OMAP4+WL1285 based Motorola Droid 4, as reported by Sebasian Reichel and the Logic PD i.MX6Q + WL1837MOD.
This reverts commit a2e02f38eff84f199c8e32359eb213f81f270047.
