platform/x86: serdev_helpers: Check for serial_ctrl_uid == NULL

2025-02-17T10:36:08+00:00

commit 478b00a623d6c8ae23a1be7bcc96cb5497045cef upstream. dell_uart_bl_pdev_probe() calls get_serdev_controller() with the serial_ctrl_uid parameter set to NULL. In case of errors this NULL parameter then gets passed to pr_err() as argument matching a "%s" conversion specification. This leads to compiler warnings when building with "make W=1". Check serial_ctrl_uid before passing it to pr_err() to avoid these.

platform/x86: acer-wmi: Ignore AC events

2025-02-17T10:36:07+00:00

[ Upstream commit f6bfa25c6665f8721421ea94fe506cc22f1d4b43 ] On the Acer Swift SFG14-41, the events 8 - 1 and 8 - 0 are printed on AC connect/disconnect. Ignore those events to avoid spamming the kernel log with error messages.

platform/x86: int3472: Check for adev == NULL

[ Upstream commit cd2fd6eab480dfc247b737cf7a3d6b009c4d0f1c ] Not all devices have an ACPI companion fwnode, so adev might be NULL. This can e.g. (theoretically) happen when a user manually binds one of the int3472 drivers to another i2c/platform device through sysfs. Add a check for adev not being set and return -ENODEV in that case to avoid a possible NULL pointer deref in skl_int3472_get_acpi_buffer().
