Move the second part of the HP laptop disk protection functionality (a red led) to the same driver. From a purely Linux developer's point of view, the led and the accelerometer have nothing related. However, they correspond to the same ACPI functionality, and so will always be used together, moreover as they share the same ACPI PNP alias, there is no other simple to allow to have same loaded at the same time if they are not in the same module. Also make it requires the led class to compile and update the Kconfig text.

|
LEDs from both userspace and optionally, by kernel events (triggers).

This is not related to standard keyboard LEDs which are controlled
|

This driver makes the mail LED accessible from userspace

programs through the leds subsystem. This LED have three

known mode: off, blink at 0.5Hz and blink at 1Hz.
|
|
|

The driver supports two kinds of interface: using ledtrig-timer
|
|
or through /sys/class/leds/clevo::mail/brightness. As this LED
|
|
cannot change it's brightness it blinks instead. The brightness
|
|
value 0 means off, 1..127 means blink at 0.5Hz and 128..255 means
|
|
blink at 1Hz.

This module can drive the mail LED for the following notebooks:
