2015-08-28mlx5: Fix missing device local_dma_lkeySagi Grimberg2-1/+30
The mlx5 driver exposes device capability IB_DEVICE_LOCAL_DMA_LKEY but does not set the the device local_dma_lkey. This breaks rpcrdma drivers.

2015-08-28Input: max8997_haptic - fix module aliasJavier Martinez Canillas1-2/+1
The driver is a platform driver and not a I2C driver so its modalias should be exported with MODULE_DEVICE_TABLE(platform,...) instead of MODULE_DEVICE_TABLE(i2c,...). Also, remove the unnecessary MODULE_ALIAS("platform:max8997-haptic") now that the correct module alias is created.

2015-08-28sfc: Allow driver to cope with a lower number of VIs than it needs for RSSShradha Shah6-28/+72
Previously, the driver would refuse to load if it couldn't secure enough VIs from the MC to fulfill its RSS requirements. This was causing probe to fail on later functions in configurations where we'd run out of VIs, such as having many VFs. This change allows the driver to load with fewer VIs, down to a minimum of 2. A warning will be printed saying that RSS requirements were not met, possibly affecting performance. efx->max_tx_channels needs to be set to avoid going down the failure path in efx_probe_nic() immediately in the loop after the probe() NIC-type function. Also, Set rc=ENOSPC when bombing out of efx_probe_nic due to lack of VIs. Signed-off-by: Shradha Shah <sshah@solarflare.com> Signed-off-by: David S. Miller <davem@davemloft.net>

Given that statistics are requested on an irregular basis, an overflow of the hardware counter can go unnoticed.

Stop building scsi_dh as a separate module and integrate it fully into the core SCSI code with explicit callouts at bus scan time. For now the callouts are placed at the same point as the old bus notifiers were called, but in the future we will be able to look at ALUA INQUIRY data earlier on. Note that this also means that the device handler modules need to be loaded by the time we scan the bus. The next patches will add support for autoloading device handlers at bus scan time to make sure they are always loaded if they are enabled in the kernel config.

A platform device can be used to provide some specific resources in order to manage the controller. In this first patch we retrieve the reset gpio which is used to power on/off the controller. The main issue is to match the current tty with the correct pdev. In case of ACPI, we can easily find the right tty/pdev pair because they are both child of the same UART port. If controller is powered-on from the driver, we need to wait for a HCI boot event before being able to send any command.

2015-08-28thinkpad_acpi: Remove side effects from vdbg_printk -> no_printk macroJoe Perches1-1/+1
vdbg_printk when not using CONFIG_THINKPAD_ACPI_DEBUG uses no_printk which produces no logging output but always evaluates arguments. Change the macro to surround the no_printk call with do { if (0) no_printk(...); } while (0) to avoid the unnecessary argument evaluations. $ size drivers/platform/x86/thinkpad_acpi.o* text data bss dec hex filename 60918 6184 824 67926 10956 drivers/platform/x86/thinkpad_acpi.o.new 60927 6184 824 67935 1095f drivers/platform/x86/thinkpad_acpi.o.old Signed-off-by: Joe Perches <joe@perches.com> Acked-by: Henrique de Moraes Holschuh <hmh@hmh.eng.br> Signed-off-by: Darren Hart <dvhart@linux.intel.com>
2015-08-28regulator: core: use debug level print in regulator_check_drmsArchit Taneja1-1/+1
When calling regulator_set_load, regulator_check_drms prints and returns an error if the regulator device's flag REGULATOR_CHANGE_DRMS isn't set. drms_uA_update, however, bails out without reporting an error. Replace the error print with a debug level print so that we don't get such prints when the underlying regulator doesn't support DRMS.

2015-08-28drm/i915: set CDCLK if DPLL0 enabled during resuming from S3Gary Wang1-8/+5
Since BIOS RC 1.4 it would enable CDCLK PLL during BIOS S3 resume, then driver needs to set CDCLK to avoid display corruption if DPLL0 enabled.
