Merge tag 'input-for-v6.16-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input

Pull input updates from Dmitry Torokhov:

 - support for Acer NGR 200 Controller added to xpad driver

 - xpad driver will no longer log errors about URBs at sudden disconnect

 - a fix for potential NULL dereference in cs40l50-vibra driver

 - several drivers have been switched to using scnprintf() to suppress
   warnings about potential output truncation
