When fixdep detects CONFIG_IS_ENABLED and other similar macros, it must parse the macro parameter to determine which actual CONFIG_ option is being referenced. This involves moving a pointer forward through the entire CONFIG_ option "word". Currently, the code uses variable q to walk through the word, but doesn't actually initialize it to point at the parameter before doing so. Consequently, the walking process immediately fails since it sees the macro invocatoins's ( rather than the expected alpha-numeric characters in the macro parameter. Fix this by adding the missing initialization.

Applied to u-boot/master, thanks!
