Introduce pcim_alloc_irq_vectors(), a device-managed version of pci_alloc_irq_vectors(), In some i2c drivers, If pcim_enable_device() has been called before, then pci_alloc_irq_vectors() is actually a device-managed function. It is used as a device-managed function, So replace it with pcim_alloc_irq_vectors(). Changelog --------- v4 -> v5: - Remove the check of enable device in pcim_alloc_irq_vectors() and make it as a static line function. - Modify the subject name in patch 3 and patch 4. v3 -> v4: - add some commit comments for patch 3 v2 -> v3: - Add some commit comments for replace some codes in pcim_release() by pci_free_irq_vectors(). - Simplify the error handling path in i2c designware driver. v1 -> v2: - Use pci_free_irq_vectors() to replace some code in pcim_release(). - Modify some commit messages.
