fixdep: fix CONFIG_IS_ENABLED etc. handling
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. Fixes: 67f2ee86ccbe ("kbuild: fixdep: Resync this with v4.17") Fixes: 7012865e961c ("gpio: fix test.py for gpio label lookup") Signed-off-by: Stephen Warren <swarren@nvidia.com> Reviewed-by: Simon Glass <sjg@chromium.org>
