2021-01-04USB: usblp: fix DMA to stackJohan Hovold
Stack-allocated buffers cannot be used for DMA (on all architectures). Replace the HP-channel macro with a helper function that allocates a dedicated transfer buffer so that it can continue to be used with arguments from the stack. Note that the buffer is cleared on allocation as usblp_ctrl_msg() returns success also on short transfers (the buffer is only used for debugging).

2021-01-04platform/x86: touchscreen_dmi: Add swap-x-y quirk for Goodix touchscreen on ↵Hans de Goede
Estar Beauty HD tablet The Estar Beauty HD (MID 7316R) tablet uses a Goodix touchscreen, with the X and Y coordinates swapped compared to the LCD panel. Add a touchscreen_dmi entry for this adding a "touchscreen-swapped-x-y" device-property to the i2c-client instantiated for this device before the driver binds. This is the first entry of a Goodix touchscreen to touchscreen_dmi.c, so far DMI quirks for Goodix touchscreen's have been added directly to drivers/input/touchscreen/goodix.c. Currently there are 3 DMI tables in goodix.c: 1. rotated_screen[] for devices where the touchscreen is rotated 180 degrees vs the LCD panel 2. inverted_x_screen[] for devices where the X axis is inverted 3. nine_bytes_report[] for devices which use a non standard touch report size Arguably only 3. really needs to be inside the driver and the other 2 cases are better handled through the generic touchscreen DMI quirk mechanism from touchscreen_dmi.c, which allows adding device-props to any i2c-client. Esp. now that goodix.c is using the generic touchscreen_properties code. Alternative to the approach from this patch we could add a 4th dmi_system_id table for devices with swapped-x-y axis to goodix.c, but that seems undesirable.

2021-01-04platform/x86: i2c-multi-instantiate: Don't create platform device for ↵Heikki Krogerus
INT3515 ACPI nodes There are several reports about the tps6598x causing interrupt flood on boards with the INT3515 ACPI node, which then causes instability. There appears to be several problems with the interrupt. One problem is that the I2CSerialBus resources do not always map to the Interrupt resource with the same index, but that is not the only problem. We have not been able to come up with a solution for all the issues, and because of that disabling the device for now. The PD controller on these platforms is autonomous, and the purpose for the driver is primarily to supply status to the userspace, so this will not affect any functionality.

2021-01-04platform/surface: SURFACE_PLATFORMS should depend on ACPIGeert Uytterhoeven
All Microsoft Surface platform-specific device drivers depend on ACPI, but the gatekeeper symbol SURFACE_PLATFORMS does not. Hence when the user is configuring a kernel without ACPI support, he is still asked about Microsoft Surface drivers, even though this question is irrelevant.

2020-12-30intel_idle: add SnowRidge C-state tableArtem Bityutskiy
Add C-state table for the SnowRidge SoC which is found on Intel Jacobsville platforms. The following has been changed. 1. C1E latency changed from 10us to 15us. It was measured using the open source "wult" tool (the "nic" method, 15us is the 99.99th percentile). 2. C1E power break even changed from 20us to 25us, which may result in less C1E residency in some workloads. 3. C6 latency changed from 50us to 130us. Measured the same way as C1E. The C6 C-state is supported only by some SnowRidge revisions, so add a C-state table commentary about this. On SnowRidge, C6 support is enumerated via the usual mechanism: "mwait" leaf of the "cpuid" instruction. The 'intel_idle' driver does check this leaf, so even though C6 is present in the table, the driver will only use it if the CPU does support it.

2020-12-30cpufreq: intel_pstate: Fix fast-switch fallback pathRafael J. Wysocki
When sugov_update_single_perf() falls back to the "frequency" path due to the missing scale-invariance, it will call cpufreq_driver_fast_switch() via sugov_fast_switch() and the driver's ->fast_switch() callback will be invoked, so it must not be NULL. However, after commit a365ab6b9dfb ("cpufreq: intel_pstate: Implement the ->adjust_perf() callback") intel_pstate sets ->fast_switch() to NULL when it is going to use intel_cpufreq_adjust_perf(), which is a mistake, because on x86 the scale-invariance may be turned off dynamically, so modify it to retain the original ->adjust_perf() callback pointer.

2020-12-30USB: Gadget: dummy-hcd: Fix shift-out-of-bounds bugAlan Stern
The dummy-hcd driver was written under the assumption that all the parameters in URBs sent to its root hub would be valid. With URBs sent from userspace via usbfs, that assumption can be violated. In particular, the driver doesn't fully check the port-feature values stored in the wValue entry of Clear-Port-Feature and Set-Port-Feature requests. Values that are too large can cause the driver to perform an invalid left shift of more than 32 bits. Ironically, two of those left shifts are unnecessary, because they implement Set-Port-Feature requests that hubs are not required to support, according to section 11.24.2.13 of the USB-2.0 spec. This patch adds the appropriate checks for the port feature selector values and removes the unnecessary feature settings. It also rejects requests to set the TEST feature or to set or clear the INDICATOR and C_OVERCURRENT features, as none of these are relevant to dummy-hcd's root-hub emulation.

With MAX_PWM being defined to 255 the code unsigned long period; ... period = ctx->pwm->args.period; state.duty_cycle = DIV_ROUND_UP(pwm * (period - 1), MAX_PWM); calculates a too small value for duty_cycle if the configured period is big (either by discarding the 64 bit value ctx->pwm->args.period or by overflowing the multiplication).

2020-12-29PHY: Ingenic: fix unconditional build of phy-ingenic-usbAlexander Lobakin
Currently drivers/phy/ingenic/Makefile adds phy-ingenic-usb to targets not depending on actual Kconfig symbol CONFIG_PHY_INGENIC_USB, so this driver always gets built[-in] on every system. Add missing dependency. Fixes: 31de313dfdcf ("PHY: Ingenic: Add USB PHY driver using generic PHY framework.")

2020-12-29qcom: bam_dma: Delete useless kfree codeZheng Yongjun
The parameter of kfree function is NULL, so kfree code is useless, delete it. Therefore, goto expression is no longer needed, so simplify it.

2020-12-29dmaengine: dw-edma: Fix use after free in dw_edma_alloc_chunk()Dan Carpenter
If the dw_edma_alloc_burst() function fails then we free "chunk" but it's still on the "desc->chunk->list" list so it will lead to a use after free. Also the "->chunks_alloc" count is incremented when it shouldn't be. In current kernels small allocations are guaranteed to succeed and dw_edma_alloc_burst() can't fail so this will not actually affect runtime.
