2012-03-08USB: serial: metro-usb: move to use dev_dbg() instead of dbg()Greg Kroah-Hartman
This properly ties the driver into the dynamic debug system and provides the needed device identification when the messages are printed out. It also removes a ton of checkpatch warnings as well, which is always a nice validation that it's the correct thing to do.

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: cdc-wdm: adding usb_cdc_wdm_register subdriver supportBjørn Mork
This driver can be used as a subdriver of another USB driver, allowing it to export a Device Managment interface consisting of a single interrupt endpoint with no dedicated USB interface. Some devices provide a Device Management function combined with a wwan function in a single USB interface having three endpoints (bulk in/out + interrupt). If the interrupt endpoint is used exclusively for DM notifications, then this driver can support that as a subdriver provided that the wwan driver calls the appropriate entry points on probe, suspend, resume, pre_reset, post_reset and disconnect. The main driver must have full control over all interface related settings, including the needs_remote_wakeup flag. A manage_power function must be provided by the main driver. A manage_power stub doing direct flag manipulation is used in normal driver mode.

2012-03-08usb: cdc-wdm: adding list lookup indirectionBjørn Mork
Register all interfaces handled by this driver in a list, getting rid of the dependency on usb_set_intfdata. This allows further generalization and simplification of the probe/create functions. This is needed to decouple wdm_open from the driver owning the interface, and it also allows us to share all the code in wdm_create with drivers unable to do usb_set_intfdata.

2012-03-07dm raid: set MD_CHANGE_DEVS when rebuildingJonathan E Brassow
The 'rebuild' parameter is used to rebuild individual devices in an array (e.g. resynchronize a RAID1 device or recalculate a parity device in higher RAID). The MD_CHANGE_DEVS flag must be set when this parameter is given in order to write out the superblocks and make the change take immediate effect. The code that handles new devices in super_load already sets MD_CHANGE_DEVS and 'FirstUse'. (The 'FirstUse' flag was being set as a special case for rebuilds in super_init_validation.)

This patch fixes a crash by recognising discards in dm_io. Currently dm_mirror can send REQ_DISCARD bios if running over a discard-enabled device and without support in dm_io the system crashes badly. BUG: unable to handle kernel paging request at 00800000 IP: __bio_add_page.part.17+0xf5/0x1e0 ... bio_add_page+0x56/0x70 dispatch_io+0x1cf/0x240 [dm_mod] ? km_get_page+0x50/0x50 [dm_mod] ? vm_next_page+0x20/0x20 [dm_mod] ? mirror_flush+0x130/0x130 [dm_mirror] dm_io+0xdc/0x2b0 [dm_mod] ...

2012-03-07dm ioctl: do not leak argv if target message only contains whitespaceJesper Juhl
If 'argc' is zero we jump to the 'out:' label, but this leaks the (unused) memory that 'dm_split_args()' allocated for 'argv' if the string being split consisted entirely of whitespace. Jump to the 'out_argv:' label instead to free up that memory. Signed-off-by: Jesper Juhl <jj@chaosbits.net> Cc: stable@kernel.org Signed-off-by: Alasdair G Kergon <agk@redhat.com>

2012-03-07hwmon: (zl6100) Maintain delay parameter in driver instance dataGuenter Roeck
A global delay parameter has the side effect of being overwritten with 0 if a single ZL2004 or ZL6105 is instantiated. If other chips supported by the same driver are in the system, this will result in access errors for those chips. To solve the problem, keep a per-instance copy of the delay parameter, and do not change the original parameter.
