From 185d566bcd0a8e83fe762b3bbef1d58347b9a034 Mon Sep 17 00:00:00 2001 From: Rob Herring Date: Wed, 4 Jun 2014 16:12:03 -0700 Subject: checkpatch: fix wildcard DT compatible string checking We attempt to search for compatible strings which use a variable token in the documented name such as or . While this was attempted to be handled, it's utterly broken. The desired forms of matching are: vendor,-* vendor,name-* For , lower case characters and numbers are permitted. For , only numeric values are allowed. With this change, the number of missing compatible strings reported in arch/arm/boot/dts is reduced from 1071 to 960.
