PCI: aardvark: Refactor unmasking summary MSI interrupt
Refactor the masking of ISR0/1 Sources and unmasking of summary MSI interrupt so that it corresponds to the comments: - first mask all ISR0/1 - then unmask all MSIs - then unmask summary MSI interrupt Link: https://lore.kernel.org/r/20220110015018.26359-10-kabel@kernel.org Signed-off-by: Pali Rohár <pali@kernel.org> Signed-off-by: Marek Behún <kabel@kernel.org> Signed-off-by: Lorenzo Pieralisi <lorenzo.pieralisi@arm.com>
