X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=866a8c87c4e51046602387953bbef76992107bcb;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git msi: Fix msi_remove_pci_irq_vectors. Since msi_remove_pci_irq_vectors is designed to be called during hotplug remove it is actively wrong to query the hardware and expect meaningful results back. To that end remove the pci_find_capability calls. Testing dev->msi_enabled and dev->msix_enabled gives us all of the information we need. Signed-off-by: Eric W.
