Subject: [patch V2 17/21] PCI/MSI: Use msi_domain_alloc/free_irqs_all_locked()
Date: Mon, 21 Nov 2022 15:36:39 +0100 (CET) [thread overview]
Message-ID: <20221121083326.451412447@linutronix.de> (raw)
In-Reply-To: 20221121083210.309161925@linutronix.de
Switch to the new domain id aware interfaces to phase out the previous
ones.
This uses the _all() variants of the MSI allocation/free interfaces
because due to potentially sparse indices of the preallocated MSI
descriptors describing the range precisely is not possible.
No functional change.
