Subject: kconfig: use T_WORD instead of T_VARIABLE for variables
X-Git-Url: https://jxself.org/git/?a=commitdiff_plain;h=800db6e4d8853227062024e8d842f962924d39a6;p=carl9170fw.git

kconfig: use T_WORD instead of T_VARIABLE for variables

There is no grammatical ambiguity by using T_WORD for variables.
The parser can distinguish variables from symbols from the context.
