* platform/x86: intel-vbtn: match power button on press rather than releaseMario Limonciello2017-08-051-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | This fixes a problem where the system gets stuck in a loop unable to wakeup via power button in s2idle. The problem happens because: - press power button: - system emits 0xc0 (power press), event ignored - system emits 0xc1 (power release), event processed, emited as KEY_POWER - set wakeup_mode to true - system goes to s2idle - press power button - system emits 0xc0 (power press), wakeup_mode is true, system wakes - system emits 0xc1 (power release), event processed, emited as KEY_POWER - system goes to s2idle again To avoid this situation, process the presses (which matches what intel-hid does too).

* platform/x86: dell-wmi: Fix driver interface version queryAndy Lutomirski2017-08-021-5/+7
| | | | | | | | | | | | | | | | | | | | When I converted dell-wmi to the new bus infrastructure, I left the call to dell_wmi_check_descriptor_buffer() in dell_wmi_init(). This could cause two problems: - An error message when loading the driver on a system without dell-wmi. We'd try to read the event descriptor even if the WMI GUID wasn't there. - A possible race if dell-wmi was loaded manually before wmi was fully initialized. Fix it by moving the call to the probe function where it belongs.

Replace custom debugging infrastructure with standard logging functions, taking advantage of dynamic debug. Replace a pr_info() call inside an ACPI callback with an acpi_handle_info() call. The following mapping was used: - FUJLAPTOP_DBG_ERROR -> acpi_handle_err() - FUJLAPTOP_DBG_WARN -> acpi_handle_info() / dev_info() - FUJLAPTOP_DBG_INFO -> acpi_handle_debug() - FUJLAPTOP_DBG_TRACE -> acpi_handle_debug() / dev_dbg() This means that some events which used to only be logged when the user explicitly requested it will now be logged by default: - ACPI method evaluation errors, - unknown ACPI notification codes, - unknown hotkey scancodes. The first type of events should happen rarely, if ever at all. The rest is interesting from driver development perspective as their presence in the logs will mean the driver is unaware of certain events, handling of which should be implemented.

There is no need to call these methods again every time the module is loaded because they only initialize status flags and hotkey-related variables; status flags are effectively constants, hotkey-related variables may be assigned non-zero values before acpi_fujitsu_laptop_add() is called, but that does not really matter as we drain the scancodes queued in the firmware's ring buffer before doing anything else. Remove sections of code which invoke and check evaluation status of the _INI methods belonging to the ACPI devices handled by the driver.

Given the ACPI paths of these two devices (\_SB.PCI0.LPCB.FJEX, \_SB.FEXT), their parent devices are also not power manageable. These parent devices will thus have their power state initialized to ACPI_STATE_D0, which in turn causes the power state for both FUJ02B1 and FUJ02E3 to always be ACPI_STATE_D0 ("on"). Remove relevant acpi_bus_update_power() calls along with parts of debug messages that they were supposed to have an effect on.
