Subject: [PATCH] PCI: hv: Take a const cpumask in hv_compose_msi_req_get_cpu()
Date: Thu, 7 Jul 2022 19:49:31 -0500 [thread overview]
Message-ID: <20220708004931.1672-1-samuel@sholland.org> (raw)
The cpumask that is passed to this function ultimately comes from
irq_data_get_effective_affinity_mask(), which was recently changed to
return a const cpumask pointer. The first level of functions handling
the affinity mask were updated, but not this helper function.
Fixes: 4d0b8298818b ("genirq: Return a const cpumask from irq_data_get_affinity_mask")
Reported-by: kernel test robot <lkp@intel.com>
