Subject: [PATCH] powerpc: use a common vio_match_device routine
X-Git-Tag: v2.6.18-rc1~1081^2~225^2~124
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=dd721ffd95d5e1516380da0b254ef737582a258f;p=karo-tx-linux.git

[PATCH] powerpc: use a common vio_match_device routine

This requires the compatible properties having vaules that are empty
strings instead of just being empty properties.
