Subject: [PATCH 05/16] staging: vchiq_core: get the rid of vchiq_static_assert
Date: Thu,  3 Jun 2021 17:49:54 +0200	[thread overview]
Message-ID: <1622735405-9980-6-git-send-email-stefan.wahren@i2se.com> (raw)
In-Reply-To: <1622735405-9980-1-git-send-email-stefan.wahren@i2se.com>

Use static_assert from the kernel instead of opencode it.
