We pass a ResetType argument to the Resettable class enter phase method, but we don't pass it to hold and exit, even though the callsites have it readily available. This means that if a device cared about the ResetType it would need to record it in the enter phase method to use later on. Pass the type to all three of the phase methods to avoid having to do that. Commit created with for dir in hw target include; do \ spatch --macro-file scripts/cocci-macro-file.h \ --sp-file scripts/coccinelle/reset-type.cocci \ --keep-comments --smpl-spacing --in-place \ --include-headers --dir $dir; done and no manual edits.
