Hello Dejin, [...] > add pcim_alloc_irq_vectors(), a explicit device-managed version of > pci_alloc_irq_vectors(). It would be "Add" at the start of the sentence. You could also drop the "explicit" word or replace it with "an explicit", if you want to keep it. Generally, this commit message could be improved - you could explain that you are updating the documentation to reflect the addition of this new function called pcim_alloc_irq_vectors(), and also briefly explain why it was added, etc. [...] > devm_pci_remap_cfg_resource() : ioremap PCI configuration space resource > + pcim_alloc_irq_vectors() : managed irq vectors allocation [...] It would be "IRQ" here.
