git://git.kernel.org/pub/scm/linux/kernel/git/jbarnes/pci Pull PCI changes (including maintainer change) from Jesse Barnes: "This pull has some good cleanups from Bjorn and Yinghai, as well as some more code from Yinghai to better handle resource re-allocation when enabled. There's also a new initcall_debug feature from Arjan which will print out quirk timing information to help identify slow quirks for fixing or refinement (Yinghai sent in a few patches to do just that once the new debug code landed). Beyond that, I'm handing off PCI maintainership to Bjorn Helgaas. He's been a core PCI and Linux contributor for some time now, and has kindly volunteered to take over. I just don't feel I have the time for PCI review and work that it deserves lately (I've taken on some other projects), and haven't been as responsive lately as I'd like, so I approached Bjorn asking if he'd like to manage things. He's going to give it a try, and I'm confident he'll do at least as well as I have in keeping the tree managed, patches flowing, and keeping things stable." Fix up some fairly trivial conflicts due to other cleanups (mips device resource fixup cleanups clashing with list handling cleanup, ppc iseries removal clashing with pci_probe_only cleanup etc) * 'linux-next' of git://git.kernel.org/pub/scm/linux/kernel/git/jbarnes/pci: (112 commits) PCI: Bjorn gets PCI hotplug too PCI: hand PCI maintenance over to Bjorn Helgaas unicore32/PCI: move <asm-generic/pci-bridge.h> include to asm/pci.h sparc/PCI: convert devtree and arch-probed bus addresses to resource powerpc/PCI: allow reallocation on PA Semi powerpc/PCI: convert devtree bus addresses to resource powerpc/PCI: compute I/O space bus-to-resource offset consistently arm/PCI: don't export pci_flags PCI: fix bridge I/O window bus-to-resource conversion x86/PCI: add spinlock held check to 'pcibios_fwaddrmap_lookup()' PCI / PCIe: Introduce command line option to disable ARI PCI: make acpihp use __pci_remove_bus_device instead PCI: export __pci_remove_bus_device PCI: Rename pci_remove_behind_bridge to pci_stop_and_remove_behind_bridge PCI: Rename pci_remove_bus_device to pci_stop_and_remove_bus_device PCI: print out PCI device info along with duration PCI: Move "pci reassigndev resource alignment" out of quirks.c PCI: Use class for quirk for usb host controller fixup PCI: Use class for quirk for ti816x class fixup PCI: Use class for quirk for intel e100 interrupt fixup ...

2012-03-08USB: serial: metro-usb: remove unneeded cast and function callGreg Kroah-Hartman
We should use kzalloc() instead of kmalloc() and memset(), and remove an unneeded void * cast as well. Cc: Aleksey Babahin <tamerlan311@gmail.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2012-03-08USB: serial: metro-usb: remove function header commentsGreg Kroah-Hartman
They aren't needed, make the checkpatch tool unhappy, and in some places, aren't even correct. So just remove them, they get in the way and are messy. Cc: Aleksey Babahin <tamerlan311@gmail.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2012-03-08USB: serial: metro-usb: remove function prototypesGreg Kroah-Hartman
By rearranging the functions a bit, we can remove all function prototypes. Note, this also deleted the _close function, as it wasn't needed, it was doing the same thing the cleanup function did, so just call that instead.

2012-03-08USB: serial: metro-usb: fix up coding style errorsGreg Kroah-Hartman
This fixes up all of the coding style errors, and removes the initial, unneeded comments on how to load the module and the old changelog which are no longer needed. There are still a number of coding style warnings left, I'll get to them later. Cc: Aleksey Babahin <tamerlan311@gmail.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2012-03-08USB: serial: metro-usb: remove the .h fileGreg Kroah-Hartman
A driver doesn't need a .h file just for simple things like vendor ids and a private structure. So move it into the .c file instead, saving some overall lines. Cc: Aleksey Babahin <tamerlan311@gmail.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2012-03-08USB: serial: metro-usb: convert to use module_usb_serial_driverGreg Kroah-Hartman
Now that we aren't doing anything special in the init function, move to use the easier module_usb_serial_driver() call instead, saving a lot of lines of unnecessary code. Cc: Aleksey Babahin <tamerlan311@gmail.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
