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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Calling acpi_bus_update_power() for ACPI devices FUJ02B1 and FUJ02E3 is pointless as they are not power manageable (neither _PS0 nor _PR0 is defined for any of them), which causes their power state to be inherited from their parent devices. 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.

Not all models have ON token - they may have multiple AUTO tokens instead. Models which do not use SMBIOS token to control keyboard backlight, also have this issue.
