@ -148,3 +148,17 @@ Why: The 8250 serial driver now has the ability to deal with the differences
brother on Alchemy SOCs. The loss of features is not considered an
issue.
Who: Ralf Baechle <ralf@linux-mips.org>
---------------------------
What: Legacy /proc/pci interface (PCI_LEGACY_PROC)
When: March 2006
Why: deprecated since 2.5.53 in favor of lspci(8)
Who: Adrian Bunk <bunk@stusta.de>
---------------------------
What: pci_module_init(driver)
When: January 2007
Why: Is replaced by pci_register_driver(pci_driver).
Who: Richard Knutsson <ricknu-0@student.ltu.se> and Greg Kroah-Hartman <gregkh@suse.de>
