2020-01-17mtd: spi-nor: Fix selection of 4-byte addressing opcodes on SpansionVignesh Raghavendra
mtd->size is still unassigned when running spansion_post_sfdp_fixups() hook, therefore use nor->params.size to determine the size of flash device. This makes sure that 4-byte addressing opcodes are used on Spansion flashes that are larger than 16MiB and don't have SFDP 4BAIT table populated.

2020-01-17x86/resctrl: Check monitoring static key in the MBM overflow handlerXiaochen Shen
Currently, there are three static keys in the resctrl file system: rdt_mon_enable_key and rdt_alloc_enable_key indicate if the monitoring feature and the allocation feature are enabled, respectively. The rdt_enable_key is enabled when either the monitoring feature or the allocation feature is enabled. If no monitoring feature is present (either hardware doesn't support a monitoring feature or the feature is disabled by the kernel command line option "rdt="), rdt_enable_key is still enabled but rdt_mon_enable_key is disabled. MBM is a monitoring feature. The MBM overflow handler intends to check if the monitoring feature is not enabled for fast return. So check the rdt_mon_enable_key in it instead of the rdt_enable_key as former is the more accurate check.

2020-01-17USB: usbfs: Always unlink URBs in reverse orderAlan Stern
When the kernel unlinks a bunch of URBs for a single endpoint, it should always unlink them in reverse order. This eliminates any possibility that some URB x will be unlinked before it can execute but the following URB x+1 will execute before it can be unlinked. Such an event would be bad, for obvious reasons. Chris Dickens pointed out that usbfs doesn't behave this way when it is unbound from an interface. All pending URBs are cancelled, but in the order of submission. This patch changes the behavior to make the unlinks occur in reverse order. It similarly changes the behavior when usbfs cancels the continuation URBs for a BULK endpoint.

2020-01-17arm64: csum: Fix pathological zero-length callsRobin Murphy
In validating the checksumming results of the new routine, I sadly neglected to test its not-checksumming results. Thus it slipped through that the one case where @buff is already dword-aligned and @len = 0 manages to defeat the tail-masking logic and behave as if @len = 8. For a zero length it doesn't make much sense to deference @buff anyway, so just add an early return (which has essentially zero impact on performance).

2020-01-17hwmon: (core) Do not use device managed functions for memory allocationsGuenter Roeck
The hwmon core uses device managed functions, tied to the hwmon parent device, for various internal memory allocations. This is problematic since hwmon device lifetime does not necessarily match its parent's device lifetime. If there is a mismatch, memory leaks will accumulate until the parent device is released. Fix the problem by managing all memory allocations internally. The only exception is memory allocation for thermal device registration, which can be tied to the hwmon device, along with thermal device registration itself.

2020-01-17hwmon: (nct7802) Fix non-working alarm on voltagesGilles Buloz
No alarm is reported by /sys/.../inX_alarm In detail: The SMI Voltage status register is the only register giving a status for voltages, but it does not work like the non-SMI status registers used for temperatures and fans. A bit is set for each input crossing a threshold, in both direction, but the "inside" or "outside" limits info is not available. Also this register is cleared on read. Note : this is not explicitly spelled out in the datasheet, but from experiment. As a result if an input is crossing a threshold (min or max in any direction), the alarm is reported only once even if the input is still outside limits. Also if the alarm for another input is read before the one of this input, no alarm is reported at all.

PM8916 has three TX inputs that each have an (optional) internal RBIAS resistor. MIC BIAS Internal1/2 (for TX1/2) are already supported. TX3 does not have its own MIC BIAS supply, instead it is also supplied from MIC_BIAS1. Now that we have simplified the MIC BIAS Internal* implementation we can easily add support for it: Add a MIC BIAS Internal3 supply that enables the internal RBIAS resistor on TX3, and make sure to also enable the MIC_BIAS1 supply.

2020-01-17ASoC: msm8916-wcd-analog: Simplify MIC BIAS InternalStephan Gerhold
At the moment, MIC BIAS Internal* and MIC BIAS External* both reference the same register, and have a part of their initialization sequence duplicated. For example, the sequence for enabling MIC BIAS Internal1 is: I1. Enable MIC_BIAS1 supply (MICB_EN bit in CDC_A_MICB_1_EN) I2. Enable internal RBIAS (TX1_INT_RBIAS_EN bit in CDC_A_MICB_1_INT_RBIAS) The sequence for enabling MIC BIAS External1 is: E1. Enable MIC_BIAS1 supply (MICB_EN bit in CDC_A_MICB_1_EN) (E2. Ideally, make sure internal RBIAS is disabled. However, this should not happen in practice because DAPM will disable unused supplies...) Right now we have: SND_SOC_DAPM_SUPPLY("MIC BIAS Internal1", CDC_A_MICB_1_EN, 7, 0, ...) // I1 SND_SOC_DAPM_SUPPLY("MIC BIAS External1", CDC_A_MICB_1_EN, 7, 0, ...) // E1 and I2 is done in the PM event handler (pm8916_wcd_analog_enable_micbias_int1). We can simplify this by defining a common DAPM supply for I1/E1 ("MIC_BIAS1"), and one DAPM supply for I2 ("MIC BIAS Internal1"). Additional DAPM routes ensure that we also enable the MIC_BIAS1 supply for the internal and external pull up resistor. Another advantage of this is that we now disable the internal RBIAS when it is not needed. This makes it much easier to add support for MIC BIAS Internal3 as a next step.

2020-01-17Merge tag 'asoc-fix-v5.5-rc6' into asoc-5.6Mark Brown
ASoC: Fixes for v5.5 This is mostly driver specific fixes, plus an error handling fix in the core. There is a rather large diffstat for the stm32 SAI driver, this is a very large but mostly mechanical update which wraps every register access in the driver to allow a fix to the locking which avoids circular locks, the active change is much smaller and more reasonably sized.

2020-01-17regulator: vctrl-regulator: Avoid deadlock getting and setting the voltageEnric Balletbo i Serra
`cat /sys/kernel/debug/regulator/regulator_summary` ends on a deadlock when you have a voltage controlled regulator (vctrl). The problem is that the vctrl_get_voltage() and vctrl_set_voltage() calls the regulator_get_voltage() and regulator_set_voltage() and that will try to lock again the dependent regulators (the regulator supplying the control voltage). Fix the issue by exporting the unlocked version of the regulator_get_voltage() and regulator_set_voltage() API so drivers that need it, like the voltage controlled regulator driver can use it.
