From: Paul Menzel <pmenzel@xxxxxxxxxxxxx> ACPICA commit b69cbef7a83eadb102a1ff6c6f6fc5abce34805a `how_long` refers to different units in both functions, so make it more clear, what unit they expect. That also makes one comment superfluous. Link: https://github.com/acpica/acpica/commit/b69cbef7 Signed-off-by: Bob Moore <robert.moore@xxxxxxxxx> Signed-off-by: Rafael J.
