JIRA: https://issues.redhat.com/browse/RHEL-53898 Upstream Status: since v6.12 Tested: with the hid-tools test suite and some hardware commit 071b24b54d2d05fbf39ddbb27dee08abd1d713f3 Author: Dmitry Torokhov <dmitry.torokhov@gmail.com> Date: Sun Oct 27 22:31:15 2024 -0700 Input: fix regression when re-registering input handlers Commit d469647bafd9 ("Input: simplify event handling logic") introduced code that would set handler->events() method to either input_handler_events_filter() or input_handler_events_default() or input_handler_events_null(), depending on the kind of input handler (a filter or a regular one) we are dealing with. Unfortunately this breaks cases when we try to re-register the same filter (as is the case with sysrq handler): after initial registration the handler will have 2 event handling methods defined, and will run afoul of the check in input_handler_check_methods(): input: input_handler_check_methods: only one event processing method can be defined (sysrq) sysrq: Failed to register input handler, error -22 Fix this by adding handle_events() method to input_handle structure and setting it up when registering a new input handle according to event handling methods defined in associated input_handler structure, thus avoiding modifying the input_handler structure.
