2020-01-03media: intel-ipu3: Align struct ipu3_uapi_awb_fr_config_s to 32 bytesSakari Ailus
A struct that needs to be aligned to 32 bytes has a size of 28. Increase the size to 32. This makes elements of arrays of this struct aligned to 32 as well, and other structs where members are aligned to 32 mixing ipu3_uapi_awb_fr_config_s as well as other types.

2020-01-03drm/i915/dsi: Control panel and backlight enable GPIOs on BYTHans de Goede
On Bay Trail devices the MIPI power on/off sequences for DSI LCD panels do not control the LCD panel- and backlight-enable GPIOs. So far, when the VBT indicates we should use the SoC for backlight control, we have been relying on these GPIOs being configured as output and driven high by the Video BIOS (GOP) when it initializes the panel. This does not work when the device is booted with a HDMI monitor connected as then the GOP will initialize the HDMI instead of the panel, leaving the panel black, even though the i915 driver tries to output an image to it. Likewise on some device-models when the GOP does not initialize the DSI panel it also leaves the mux of the PWM0 pin in generic GPIO mode instead of muxing it to the PWM controller. This commit makes the DSI code control the SoC GPIOs for panel- and backlight-enable on BYT, when the VBT indicates the SoC should be used for backlight control. It also ensures that the PWM0 pin is muxed to the PWM controller in this case. This fixes the LCD panel not lighting up on various devices when booted with a HDMI monitor connected. This has been tested to fix this on the following devices: Peaq C1010 Point of View MOBII TAB-P800W Point of View MOBII TAB-P1005W Terra Pad 1061 Yours Y8W81 Reviewed-by: Linus Walleij <linus.walleij@linaro.org> Reviewed-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Signed-off-by: Hans de Goede <hdegoede@redhat.com> Link: https://patchwork.freedesktop.org/patch/msgid/20191216205122.1850923-6-hdegoede@redhat.com

2020-01-03drm/i915/dsi: Move Crystal Cove PMIC panel GPIO lookup from mfd to the i915 ↵Hans de Goede
driver Move the Crystal Cove PMIC panel GPIO lookup-table from drivers/mfd/intel_soc_pmic_core.c to the i915 driver. The moved looked-up table is adding a GPIO lookup to the i915 PCI device and the GPIO subsys allows only one lookup table per device, The intel_soc_pmic_core.c code only adds lookup-table entries for the PMIC panel GPIO (as it deals only with the PMIC), but we also need to be able to access some GPIOs on the SoC itself, which requires entries for these GPIOs in the lookup-table. Since the lookup-table is attached to the i915 PCI device it really should be part of the i915 driver, this will also allow us to extend it with GPIOs from other sources when necessary.

2020-01-03drm/i915/dsi: Init panel-enable GPIO to low when the LCD is initially off (v2)Hans de Goede
When the LCD has not been turned on by the firmware/GOP, because e.g. the device was booted with an external monitor connected over HDMI, we should not turn on the panel-enable GPIO when we request it. Turning on the panel-enable GPIO when we request it, means we turn it on too early in the init-sequence, which causes some panels to not correctly light up. This commits adds a panel_is_on parameter to intel_dsi_vbt_gpio_init() and makes intel_dsi_vbt_gpio_init() set the initial GPIO value accordingly. This fixes the panel not lighting up on a Thundersoft TST168 tablet when booted with an external monitor connected over HDMI.

So far we have been carrying the code to do this on BYT/CHT devices with a Crystal Cove PMIC in vlv_dsi.c, but as this really is a shortcoming of the VBT MIPI-sequences, intel_dsi_vbt.c is a better place for this, so move it there.

2020-01-03staging: vt6656: Fix non zero logical return of, usb_control_msgMalcolm Priestley
Starting with commit 59608cb1de1856 ("staging: vt6656: clean function's error path in usbpipe.c") the usb control functions have returned errors throughout driver with only logical variable checking. However, usb_control_msg return the amount of bytes transferred this means that normal operation causes errors. Correct the return function so only return zero when transfer is successful.

2020-01-02ftrace: Avoid potential division by zero in function profilerWen Yang
The ftrace_profile->counter is unsigned long and do_div truncates it to 32 bits, which means it can test non-zero and be truncated to zero for division. Fix this issue by using div64_ul() instead.

On some archs with some configurations, MCOUNT_INSN_SIZE is not defined, and this makes the stack tracer fail to compile. Just define it to zero in this case.

2020-01-02tracing: Define MCOUNT_INSN_SIZE when not defined without direct callsSteven Rostedt (VMware)
In order to handle direct calls along side of function graph tracer, a check is made to see if the address being traced by the function graph tracer is a direct call or not. To get the address used by direct callers, the return address is subtracted by MCOUNT_INSN_SIZE. For some archs with certain configurations, MCOUNT_INSN_SIZE is undefined here. But these should not be using direct calls anyway. Just define MCOUNT_INSN_SIZE to zero in this case.
