There is a bit of typo here: false should be actually 0:

Will change this in the next CL once agreed.

Replace this line 

m_orientation = DeviceOrientationData::create(alpha, alpha ? *alpha : false,
beta, beta ? *beta : false, gamma, gamma ? *gamma : false, absolute, absolute ?
*absolute : false);   

with

m_orientation = DeviceOrientationData::create(alpha, alpha ? *alpha : 0, beta,
beta ? *beta : 0, gamma, gamma ? *gamma : 0, absolute, absolute ? *absolute :
false);

     if (m_orientation->canProvideAlpha())
         return m_orientation->alpha();
 
     isNull = true;
