From: Adrien Destugues <adrien.destugues@xxxxxxxxxxxxxxxxxxxxx> ACPICA commit 49fe4f25483feec2f685b204ef19e28d92979e95 In Haiku, semaphores are represented by integers, not pointers. So, we can't use NULL as the invalid/destroyed value, the correct value is -1. Introduce a platform overridable define to allow this. Fixes #162 (which was closed after coming to the conclusion that this should be done, but the change was never done). Link: https://github.com/acpica/acpica/commit/49fe4f25 Signed-off-by: Rafael J.
