[PATCH AUTOSEL 6.14 1/5] platform/x86: fujitsu-laptop: Support Lifebook S2110 hotkeys

[Sasha Levin]

From: Valtteri Koskivuori <vkoskiv@gmail.com>

[ Upstream commit a7e255ff9fe4d9b8b902023aaf5b7a673786bb50 ]

The S2110 has an additional set of media playback control keys enabled
by a hardware toggle button that switches the keys between "Application"
and "Player" modes. Toggling "Player" mode just shifts the scancode of
each hotkey up by 4.

Add defines for new scancodes, and a keymap and dmi id for the S2110.

Tested on a Fujitsu Lifebook S2110.

[PATCH AUTOSEL 6.14 3/5] platform/x86: thinkpad_acpi: Ignore battery threshold change event notification

[Sasha Levin]

From: Mark Pearson <mpearson-lenovo@squebb.ca>

[ Upstream commit 29e4e6b4235fefa5930affb531fe449cac330a72 ]

If user modifies the battery charge threshold an ACPI event is generated.
Confirmed with Lenovo FW team this is only generated on user event. As no
action is needed, ignore the event and prevent spurious kernel logs.

[PATCH AUTOSEL 6.14 4/5] net: ethernet: ti: am65-cpsw: Lower random mac address error print to info

[Sasha Levin]

From: Nishanth Menon <nm@ti.com>

[ Upstream commit 50980d8da71a0c2e045e85bba93c0099ab73a209 ]

Using random mac address is not an error since the driver continues to
function, it should be informative that the system has not assigned
a MAC address. This is inline with other drivers such as ax88796c,
dm9051 etc. Drop the error level to info level.

[PATCH AUTOSEL 6.14 5/5] ksmbd: use list_first_entry_or_null for opinfo_get_list()

[Sasha Levin]

From: Namjae Jeon <linkinjeon@kernel.org>

[ Upstream commit 10379171f346e6f61d30d9949500a8de4336444a ]

The list_first_entry() macro never returns NULL.  If the list is
empty then it returns an invalid pointer.  Use list_first_entry_or_null()
to check if the list is empty.
