Subject: [PULL 02/20] hw/mips/loongson3_virt: Fix condition of IPI IOCSR connection
Date: Tue, 20 Aug 2024 00:50:58 +0200 [thread overview]
Message-ID: <20240819225116.17928-3-philmd@linaro.org> (raw)

From: Jiaxun Yang <jiaxun.yang@flygoat.com>
>>> CID 1547264: Null pointer dereferences (REVERSE_INULL)
>>> Null-checking "ipi" suggests that it may be null, but it has already been dereferenced on all paths leading to the check.
Resolves: Coverity CID 1547264
