Using a dedicated Kconfig option for enabling debugging means the user may be forced to recompile their kernel in order to gather debugging information, which is inconvenient. 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. Signed-off-by:

acpi_ns_initialize_devices(), which is called during system-wide ACPI initialization, already detects and calls all _INI methods belonging to objects present in ACPI tables. 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. Signed-off-by:

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. Signed-off-by: -

In the case of brightness-related FUJ02B1 ACPI device, initializing the input device associated with it identically as acpi-video initializes its input device makes sense. However, using the same data for the input device associated with the FUJ02E3 ACPI device makes little sense, because the latter has nothing to do with video and assigning an arbitrary product ID to it is redundant.

Do not check whether the pointer passed to ACPI add callbacks is NULL as it is earlier dereferenced anyway in the bus-level probe callback, acpi_device_probe(). Do not check the value of acpi_disabled in fujitsu_init(), because it is already done by acpi_bus_register_driver(), which is the first function called by fujitsu_init(). Signed-off-by:

Dell Latitude 3160 does not have keyboard backlight, but there is a sysfs interface for it, which does nothing at all. KBD_LED_ON_TOKEN is the only token can be found. Since it doesn't have KBD_LED_OFF_TOKEN or KBD_LED_AUTO_*_TOKEN, it should be safe to assume at least two tokens should be present to support keyboard backlight. 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. Brightness level is 0 on these models. Verified on Dell Inspiron 3565. Reports keyboard backlight is supported only when at least two modes are present. Signed-off-by:

object_id and notify_id are in one union structure and their meaning is defined by flags. Therefore do not print notify_id for non-event block and do not print object_id for event block. Remove also reserved member as it does not have any defined meaning or type yet. As object_id and notify_id union members overlaps and have different types, it caused that kernel print to dmesg binary data. This patch eliminates it. Signed-off-by:
