Subject: [PATCH] HID: logitech-dj: Fix forwarding of very long HID++ reports
|
||||
|
||||
The HID++ spec also defines very long HID++ reports, with a reportid of
|
||||
0x12. The MX5000 and MX5500 keyboards use 0x12 output reports for sending
|
||||
messages to display on their buildin LCD.
|
||||
|
||||
Userspace (libmx5000) supports this, in order for this to work when talking
|
||||
to the HID devices instantiated for the keyboard by hid-logitech-dj,
|
||||
we need to properly forward these reports to the device.
|
||||
|
||||
This commit fixes logi_dj_ll_raw_request not forwarding these reports.
|
||||
|
||||

Subject: [PATCH] platform/x86: asus-wmi: Only Tell EC the OS will handle
|

display hotkeys from asus_nb_wmi

|

Commit 78f3ac76d9e5 ("platform/x86: asus-wmi: Tell the EC the OS will
|
||||
handle the display off hotkey") causes the backlight to be permanently off
|
||||
on various EeePC laptop models using the eeepc-wmi driver (Asus EeePC
|
||||
1015BX, Asus EeePC 1025C).
|
||||
|
||||
The asus_wmi_set_devstate(ASUS_WMI_DEVID_BACKLIGHT, 2, NULL) call added
|
||||
by that commit is made conditional in this commit and only enabled in
|
||||
the quirk_entry structs in the asus-nb-wmi driver fixing the broken
|
||||
display / backlight on various EeePC laptop models.
