Subject: [PATCH] staging: vchiq_core: remove BITSET_ZERO
Git-commit: 1cc5a28be1fce52fa2e8d886459b6efcd1f6346e
Patch-mainline: v4.18-rc1
References: FATE#324827

Hiding memset behind a macro isn't the best, because it relies on that
the parameter is not a pointer. Luckily all user has been removed, so
we can remove BITSET_ZERO too.
