[v5,0/4] Introduce pcim_alloc_irq_vectors()

Message

Dejin Zheng Feb. 26, 2021, 3:50 p.m. UTC

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.

Bjorn, I don't see this anywhere, except mailing list. Neither your opinion.
What is the plan?
