Make two minor tweaks to acpi_fujitsu_hotkey_press() to make it more similar to acpi_fujitsu_hotkey_release(): * call vdbg_printk() after reporting the input event, * return immediately when kfifo_in_locked() fails.

/*
|
|
* fujitsu-laptop.c - Fujitsu laptop support, providing access to additional
|
|
* features made available on a range of Fujitsu laptops including the
|
|
* P2xxx/P5xxx/S6xxx/S7xxx series.
|
|
*
|
|
* This driver exports a few files in /sys/devices/platform/fujitsu-laptop/;
|
|
* others may be added at a later date.
|
|
*
|
|
* lcd_level - Screen brightness: contains a single integer in the
|
|
* range 0..7. (rw)
|
|
*
|
|
* In addition to these platform device attributes the driver
|
|
* registers itself in the Linux backlight control subsystem and is
|
|
* available to userspace under /sys/class/backlight/fujitsu-laptop/.
|
|
*
|
|
* Hotkeys present on certain Fujitsu laptops (eg: the S6xxx series) are
|
|
* also supported by this driver.
|
|
*
|
|
* This driver has been tested on a Fujitsu Lifebook S6410, S7020 and
|
|
* P8010. It should work on most P-series and S-series Lifebooks, but
|
|
* YMMV.
|
|
*
|
|
* The module parameter use_alt_lcd_levels switches between different ACPI
|
|
* brightness controls which are used by different Fujitsu laptops. In most
|
|
* cases the correct method is automatically detected. "use_alt_lcd_levels=1"
|
|
* is applicable for a Fujitsu Lifebook S6410 if autodetection fails.
