In the unlikely case of hdev vanishing while hid_debug_events_read() was sleeping, we can't really break out of the case switch as with other cases, as on the way out we'll try to remove ourselves from the hdev waitqueue. Fix this by taking a shortcut exit path and avoiding cleanup that doesn't make sense in case hdev doesn't exist any more anyway.

Current snd_soc_runtime_set_dai_fmt() is called after soc_probe_link_dais(). this means snd_soc_dai_set_fmt() will be called after soc_new_pcm(). Before appling 1efb53a220b78fdfdbb97b726a2156713e75bdab (ASoC: simple-card: Remove support for setting differing DAI formats) simple-card user had (1) snd_soc_dai_set_fmt() -> soc_new_pcm(), but, after that it is (2) soc_new_pcm() -> snd_soc_dai_set_fmt(). At least rsnd driver is assuming (1) pattern. This patch move snd_soc_dai_set_fmt() into soc_probe_link_dais() after the dai_link->init section to solve this issue.

2015-04-10lpfc: Fix premature release of rpi bit in bitmaskJames Smart
Currently, the driver plays off the fact that older sli4 adapters have a different rpi access pattern that allowed for the rpi reference to be released earlier in the teardown sequence, allowing the driver to recycle the rpi value sooner. Newer sli4 adapters have a different access pattern that requires us to wait for a later mailbox completion. This changes the put call location on the newer sli4 adapters. Symptoms of the error are "0110 ELS" and the "0372 iotag" errors.

2015-04-10lpfc: Fix host reset escalation killing all IOs.James Smart
Fix host reset escalation killing all IOs. SLI-3 adapters will use a new host template. The template differs from SLI-4 adapters in that it does not have an eh_host_reset_handler. Lpfc has traditionally never had a host_reset. The host reset handler was added when we ran into a stuck hardware condition on a SLI-4 adapter. The host_reset will reset and reinit the pci function, clearing the hardware condition. Unfortunately, the host reset handler uses attach/detach code paths, which makes scsi_add_host() and scsi_remove_host() calls. Meaning, a host_reset will completely remove the scsi_host from the system. As a new call to scsi_add_host() is made, the shost# changes, which results in completely new scsi_devices and device names. All the older scsi devices on the old shost# are now orphaned and unrecoverable. We realize we need to re-implement the host_reset_handler so the scsi_host stays registered across the host_reset, but that will be a rather lengthy effort. In the short term, we had an immediate need to restore the SLI-3 devices to their working behavior, with the easiest path being to remove their host_reset handler.

2015-04-10regulator: output current-limit for all regulators in summaryHeiko Stübner
Voltage regulators can have (unregulated) current limits too, so we should probably output both voltage and current for all regulators. Holding the rdev->mutex actually conflicts with _regulator_get_current_limit but also is not really necessary, as the global regulator_list_mutex already protects us from the regulator vanishing while we go through the list. On the rk3288-firefly the summary now looks like: regulator use open bypass voltage current min max ------------------------------------------------------------------------------- vcc_sys 0 12 0 5000mV 0mA 5000mV 5000mV vcc_lan 1 1 0 3300mV 0mA 3300mV 3300mV ff290000.ethernet 0mV 0mV vcca_33 0 0 0 3300mV 0mA 3300mV 3300mV vcca_18 0 0 0 1800mV 0mA 1800mV 1800mV vdd10_lcd 0 0 0 1000mV 0mA 1000mV 1000mV [...] Suggested-by: Mark Brown <broonie@kernel.org> Signed-off-by: Heiko Stuebner <heiko@sntech.de> Signed-off-by: Mark Brown <broonie@kernel.org>
2015-04-10regulator: add a summary tree in debugfsHeiko Stübner
On modern systems the regulator hierarchy can get quite long and nested with regulators supplying other regulators. In some cases when debugging it might be nice to get a tree of these regulators, their consumers and the regulation constraints in one go. To achieve this add a regulator_summary sysfs node, similar to clk_summary in the common clock framework, that walks the regulator list and creates a tree out of the regulators, their consumers and core per-regulator settings. On a rk3288-firefly the regulator_summary would for example look something like: regulator use open bypass value min max ----------------------------------------------------------------------- vcc_sys 0 12 0 5000mV 5000mV 5000mV vcc_lan 1 1 0 3300mV 3300mV 3300mV ff290000.ethernet 0mV 0mV vcca_33 0 0 0 3300mV 3300mV 3300mV vcca_18 0 0 0 1800mV 1800mV 1800mV vdd10_lcd 0 0 0 1000mV 1000mV 1000mV vccio_sd 0 0 0 3300mV 3300mV 3300mV vcc_20 0 3 0 2000mV 2000mV 2000mV vcc18_lcd 0 0 0 1800mV 1800mV 1800mV vcc_18 0 2 0 1800mV 1800mV 1800mV ff100000.saradc 0mV 0mV ff0d0000.dwmmc 1650mV 1950mV vdd_10 0 0 0 1000mV 1000mV 1000mV vdd_log 0 0 0 1100mV 1100mV 1100mV vcc_io 0 3 0 3300mV 3300mV 3300mV ff0f0000.dwmmc 3300mV 3400mV vcc_flash 1 1 0 1800mV 1800mV 1800mV ff0f0000.dwmmc 1700mV 1950mV vcc_sd 1 1 0 3300mV 3300mV 3300mV ff0c0000.dwmmc 3300mV 3400mV vcc_ddr 0 0 0 1200mV 1200mV 1200mV vdd_gpu 0 0 0 1000mV 850mV 1350mV vdd_cpu 0 1 0 900mV 850mV 1350mV cpu0 900mV 900mV vcc_5v 0 2 0 5000mV 5000mV 5000mV vcc_otg_5v 0 0 0 5000mV 5000mV 5000mV vcc_host_5v 0 0 0 5000mV 5000mV 5000mV regulator-dummy 0 0 0 0mV 0mV 0mV Signed-off-by: Heiko Stuebner <heiko@sntech.de> Signed-off-by: Mark Brown <broonie@kernel.org>

2015-04-10ACPI / scan: Take the PRP0001 position in the list of IDs into accountRafael J. Wysocki
If the special PRP0001 device ID is present in a device's _CID list, it should not prevent any ACPI/PNP IDs preceding it in the device's list of identifiers from being matched first. That is, only if none of the IDs preceding PRP0001 in the device's PNP/ACPI IDs list matches the IDs recognized by the driver, the driver's list of "compatible" IDs should be matched against the device's "compatible" property, if present. In addition to that, drivers can provide both acpi_match_table and of_match_table at the same time and the of_compatible matching should be used in that case too if PRP0001 is present in the device's list of identifiers. To make that happen, rework acpi_driver_match_device() to do the "compatible" property check in addition to matching the driver's list of ACPI IDs against the device's one. Signed-off-by: Rafael J.

Commit 32098ec7bcba ("MIPS: Makefile: Move the ASEs checks after setting the core's CFLAGS") re-arranged the MIPS ASE detection code and also added the current cflags to the detection logic. However, this introduced a few bugs. First of all, the mips-cflags should not be quoted since that ends up being passed as a string to subsequent commands leading to broken detection from the cc-option-* tools. Moreover, in order to avoid duplicating the cflags-y because of how cc-option works, we rework the logic so we pass only those cflags which are needed by the selected ASE. Finally, fix some typos resulting in MSA not being detected correctly.

2015-04-10MIPS: lose_fpu(): Disable FPU when MSA enabledJames Hogan
The lose_fpu() function only disables the FPU in CP0_Status.CU1 if the FPU is in use and MSA isn't enabled. This isn't necessarily a problem because KSTK_STATUS(current), the version of CP0_Status stored on the kernel stack on entry from user mode, does always get updated and gets restored when returning to user mode, but I don't think it was intended, and it is inconsistent with the case of only the FPU being in use. Sometimes leaving the FPU enabled may also mask kernel bugs where FPU operations are executed when the FPU might not be enabled. So lets disable the FPU in the MSA case too.

A driver was added in commit 5433acd81e87 ("MIPS: ralink: add illegal access driver") without the Kconfig section being added. Fix this by adding the symbol to the Kconfig file.
