ASoC: detect empty DMI strings

Browse source

[ Upstream commit a9683730e8 ]

Some bootloaders like recent versions of U-Boot may install some DMI
properties with empty values rather than not populate them. This manages
to make its way through the validator and cleanup resulting in a rogue
hyphen being appended to the card longname.
