2014-11-10cxgb4vf: Move fl_starv_thres into adapter->sge data structureHariprasad Shenai
Move fl_starv_thres into adapter->sge data structure since it _could_ be different from adapter to adapter. Also move other per-adapter SGE values which had been treated as driver globals into adapter->sge.

2014-11-10b43: fix NULL pointer dereference in b43_phy_copy()Hauke Mehrtens
phy_read and phy_write are not set for every phy any more sine this: commit d342b95dd735014a590f9051b1ba227eb54ca8f6 Author: Rafał Miłecki <zajec5@gmail.com> Date: Thu Jul 31 21:59:43 2014 +0200 b43: don't duplicate common PHY read/write ops b43_phy_copy() accesses phy_read and phy_write directly and will fail with some phys. This patch fixes the regression by using the b43_phy_read() and b43_phy_write() functions which should be used for read and write access.

2014-11-10mfd: Add support for Diolan DLN-2 devicesOctavian Purdila
This patch implements the USB part of the Diolan USB-I2C/SPI/GPIO Master Adapter DLN-2. Details about the device can be found here: https://www.diolan.com/i2c/i2c_interface.html. Information about the USB protocol can be found in the Programmer's Reference Manual [1], see section 1.7. Because the hardware has a single transmit endpoint and a single receive endpoint the communication between the various DLN2 drivers and the hardware will be muxed/demuxed by this driver. Each DLN2 module will be identified by the handle field within the DLN2 message header. If a DLN2 module issues multiple commands in parallel they will be identified by the echo counter field in the message header. The DLN2 modules can use the dln2_transfer() function to issue a command and wait for its response. They can also register a callback that is going to be called when a specific event id is generated by the device (e.g. GPIO interrupts). The device uses handle 0 for sending events.

2014-11-10mfd: twl4030-power: Fix poweroff with PM configuration enabledTony Lindgren
Commit e7cd1d1eb16f ("mfd: twl4030-power: Add generic reset configuration") enabled configuring the PM features for twl4030. This caused poweroff command to fail on devices that have the BCI charger on twl4030 wired, or have power wired for VBUS. Instead of powering off, the device reboots. This is because voltage is detected on charger or VBUS with the default bits enabled for the power transition registers. To fix the issue, let's just clear VBUS and CHG bits as we want poweroff command to keep the system powered off.

2014-11-10mfd: max77693: Fix always masked MUIC interruptsKrzysztof Kozlowski
All interrupts coming from MUIC were ignored because interrupt source register was masked. The Maxim 77693 has a "interrupt source" - a separate register and interrupts which give information about PMIC block triggering the individual interrupt (charger, topsys, MUIC, flash LED). By default bootloader could initialize this register to "mask all" value. In such case (observed on Trats2 board) MUIC interrupts won't be generated regardless of their mask status. Regmap irq chip was unmasking individual MUIC interrupts but the source was masked Before introducing regmap irq chip this interrupt source was unmasked, read and acked. Reading and acking is not necessary but unmasking is.

2014-11-10mfd: max77693: Use proper regmap for handling MUIC interruptsKrzysztof Kozlowski
Interrupts coming from Maxim77693 MUIC block (MicroUSB Interface Controller) were not handled at all because wrong regmap was used for MUIC's regmap_irq_chip. The MUIC component of Maxim 77693 uses different I2C address thus second regmap is created and used by max77693 extcon driver. The registers for MUIC interrupts are also in that block and should be handled by that second regmap. However the regmap irq chip for MUIC was configured with default regmap which could not read MUIC registers.

2014-11-10bnx2fc: fix tgt spinlock lockingMaurizio Lombardi
bnx2fc_queuecommand(): when allocating a new io_req, the tgt_lock spinlock must be locked before calling bnx2fc_cmd_alloc(). The spinlock should also be kept locked until bnx2fc_post_io_req() has been completed. If not, a kernel thread may call bnx2fc_process_cq_compl() that extracts the newly allocated io_req from hba->cmd_mgr->cmds and destroys it while it is still being used by bnx2fc_post_io_req().

2014-11-10scsi: TUR path is down after adapter gets reset with multipathwenxiong@linux.vnet.ibm.com
This patch fixes an issue with multipath ipr SAS devices which require a start unit command to be issued following an adapter reset. Without this patch, paths get marked failed following an adapter reset and since the error handler never gets invoked to issue the start unit, the paths are never recovered. Returning FAILED for this case ensures the error handler wakes up to issue the start unit.

2014-11-10scsi: call device handler for failed TUR commandChristoph Hellwig
Multipath devices using the TUR path checker need to see the sense code for a failed TUR command in their device handler. Since commit 14216561e164671ce147458653b1fea06a we always return success for mid layer issued TUR commands before calling the device handler, which stopped the TUR path checker from working. Move the call to the device handler check sense method before the early return for TUR commands to give the device handler a chance to intercept them.

2014-11-10scsi: only re-lock door after EH on devices that were resetChristoph Hellwig
Setups that use the blk-mq I/O path can lock up if a host with a single device that has its door locked enters EH. Make sure to only send the command to re-lock the door to devices that actually were reset and thus might have lost their state. Otherwise the EH code might be get blocked on blk_get_request as all requests for non-reset devices might be in use.
