of: fix autoloading due to broken modalias with no 'compatible'
[ Upstream commit b3c0a4dab7e35a9b6d69c0415641d2280fdefb2b ] Because of an improper dereference, a stray 'C' character was output to the modalias when no 'compatible' was specified. This is the case for some old PowerMac drivers which only set the 'name' property. Fix it to let them match again.
