Subject: [PATCH 1/4] powerpc/xive: remove dead NULL check after GFP_NOFAIL allocation
Date: Thu, 23 Jul 2026 16:18:10 +0800 [thread overview]
Message-ID: <20260723081813.176792-2-gouhao@uniontech.com> (raw)
In-Reply-To: <20260723081813.176792-1-gouhao@uniontech.com>
kzalloc_objs with the __GFP_NOFAIL flag will never return NULL, so the
subsequent NULL check is unreachable dead code. Remove it.
