Subject: of: fix autoloading due to broken modalias with no 'compatible'

From: Wolfram Sang <wsa@the-dreams.de>

commit b3c0a4dab7e35a9b6d69c0415641d2280fdefb2b upstream.

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.
