Subject: [PATCH 2/4] KVM: arm64: vgic-v5: Correctly reset h_lpi_ist to NULL
Date: Sat, 19 Sep 2026 13:31:48 +0100 [thread overview]
Message-ID: <20260919123150.3283606-3-maz@kernel.org> (raw)
In-Reply-To: <20260919123150.3283606-1-maz@kernel.org>
Resetting a pointer to 0 is not completely wrong, but sparse
legitimately shouts about it integer/pointer mix.
Use NULL as expected.
Reported-by: kernel test robot <lkp@intel.com>
Closes: https://lore.kernel.org/oe-kbuild-all/202609190952.glUgOBvp-lkp@intel.com/
