iio: accel: kxcjk-1013: reject duplicate event disable
In the Linux kernel, the following vulnerability has been resolved: iio: accel: kxcjk-1013: reject duplicate event disable The IIO core does not filter duplicate writes to the event enable attribute. kxcjk1013_write_event_config() already ignores repeated enable requests, but a repeated disable request still calls kxcjk1013_set_power_state(data, false), dropping a runtime PM reference that was not acquired for this request. This can underflow the runtime PM usage count and trigger a "Runtime PM usage count underflow" warning. Return early when the requested state already matches ev_enable_state.
