mfd: cros-ec: copy the whole event in get_next_event_xfer

2018-10-10T03:57:30Z

Commit 57e94c8b974db2d83c60e1139c89a70806abbea0 caused cros-ec keyboard events be truncated on many chromebooks so that Left and Right keys on Column 12 were always 0. Use ret as memcpy len to fix this. The old code was using ec_dev->event_size, which is the event payload/data size excluding event_type header, for the length of the memcpy operation. Use ret as memcpy length to avoid the off by one and copy the whole msg->data.

Pull x86 platform driver updates from Andy Shevchenko: - The driver for Silead touchscreen configurations has been renamed from silead_dmi to touchscreen_dmi since it starts supporting other touchscreens which require some DMI quirks It also gets expanded to cover cases for Chuwi Vi10, ONDA V891W, Connect Tablet 9, Onda V820w, and Cube KNote i1101 tablets. - Another bunch of changes is related to Mellanox platform code to allow user space to communicate with Mellanox for system control and monitoring purposes. The driver notifies user on hotplug device signal receiving. - ASUS WMI drivers recognize lid flip action on UX360, and correctly toggles airplane mode LED. In addition the keyboard backlight toggle gets support. - ThinkPad ACPI driver enables support for calculator key (on at least P52). It also has been fixed to support three characters model designators, which are used for modern laptops. Earlier the battery, marked as BAT1, on ThinkPad laptops has not been configured properly, which is fixed. On the opposite the multi-battery configurations now probed correctly. - Dell SMBIOS driver starts working on some Dell servers which do not support token interface. The regression with backlight detection has also been fixed. In order to support dock mode on some laptops, Intel virtual button driver has been fixed. The last but not least is the fix to Intel HID driver due to changes in Dell systems that prevented to use power button. * tag 'platform-drivers-x86-v4.19-1' of git://git.infradead.org/linux-platform-drivers-x86: (47 commits) platform/x86: acer-wmi: Silence "unsupported" message a bit platform/x86: intel_punit_ipc: fix build errors platform/x86: ideapad: Add Y520-15IKBM and Y720-15IKBM to no_hw_rfkill platform/x86: asus-nb-wmi: Add keymap entry for lid flip action on UX360 platform/x86: acer-wmi: refactor function has_cap platform/x86: thinkpad_acpi: Fix multi-battery bug platform/x86: thinkpad_acpi: extend battery quirk coverage platform/x86: touchscreen_dmi: Add info for the Cube KNote i1101 tablet platform/x86: mlx-platform: Fix copy-paste error in mlxplat_init() platform/x86: mlx-platform: Remove unused define platform/x86: mlx-platform: Change mlxreg-io configuration for MSN274x systems Documentation/ABI: Add new attribute for mlxreg-io sysfs interfaces platform/x86: mlx-platform: Allow mlxreg-io driver activation for more systems platform/x86: mlx-platform: Add ASIC hotplug device configuration platform/mellanox: mlxreg-hotplug: Add hotplug hwmon uevent notification platform/mellanox: mlxreg-hotplug: Improve mechanism of ASIC health discovery platform/x86: mlx-platform: Add mlxreg-fan platform driver activation platform/x86: dell-laptop: Fix backlight detection platform/x86: toshiba_acpi: Fix defined but not used build warnings platform/x86: thinkpad_acpi: Support battery quirk ...

platform/x86: acer-wmi: Silence "unsupported" message a bit

2018-08-22T10:40:24Z

This driver prints that "Unsupported machine..." message on every boot on ThinkPad X1 Carbon laptops (and I assume a number of other systems), which causes graphical boots to "glitch" a bit and is rather annoying ...

Pull core signal handling updates from Eric Biederman: "It was observed that a periodic timer in combination with a sufficiently expensive fork could prevent fork from every completing. This contains the changes to remove the need for that restart. This set of changes is split into several parts: - The first part makes PIDTYPE_TGID a proper pid type instead something only for very special cases. The part starts using PIDTYPE_TGID enough so that in __send_signal where signals are actually delivered we know if the signal is being sent to a a group of processes or just a single process. - With that prep work out of the way the logic in fork is modified so that fork logically makes signals received while it is running appear to be received after the fork completes" * 'siginfo-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace: (22 commits) signal: Don't send signals to tasks that don't exist signal: Don't restart fork when signals come in. fork: Have new threads join on-going signal group stops fork: Skip setting TIF_SIGPENDING in ptrace_init_task signal: Add calculate_sigpending() fork: Unconditionally exit if a fatal signal is pending fork: Move and describe why the code examines PIDNS_ADDING signal: Push pid type down into complete_signal. signal: Push pid type down into __send_signal signal: Push pid type down into send_signal signal: Pass pid type into do_send_sig_info signal: Pass pid type into send_sigio_to_task & send_sigurg_to_task signal: Pass pid type into group_send_sig_info signal: Pass pid and pid type into send_sigqueue posix-timers: Noralize good_sigevent signal: Use PIDTYPE_TGID to clearly store where file signals will be sent pid: Implement PIDTYPE_TGID pids: Move the pgrp and session pid pointers from task_struct to signal_struct kvm: Don't open code task_pid in kvm_vcpu_ioctl pids: Compute task_tgid using signal->leader_pid ...

This is only for GNSS receivers, but you have to start somewhere, and this is great to see.
