Input: Add IBM Operation Panel driver Add a driver to get the button events from the panel and provide them to userspace with the input subsystem. The panel is connected with I2C and controls the bus, so the driver registers as an I2C slave device.

Input: ibm-panel - use guard notation when acquiring spinlock Using guard notation makes the code more compact and error handling more robust by ensuring that locks are released in all code paths when control leaves critical section.

Input: Switch i2c drivers back to use .probe() After commit b8a1a4cd5a98 ("i2c: Provide a temporary .probe_new() call-back type"), all drivers being converted to .probe_new() and then 03c835f498b5 ("i2c: Switch .probe() to not take an id parameter") convert back to (the new) .probe() to be able to eventually drop .probe_new() from struct i2c_driver.
