commit e8eded55f2372406e872282914a48adcba5dfeef Author: Vladimir Kondratyev <[email protected]> AuthorDate: 2020-12-24 19:08:04 +0000 Commit: Vladimir Kondratyev <[email protected]> CommitDate: 2021-02-05 10:17:52 +0000 ukbd(4): Push LED events in ioctl handler rather than in xfer callback If LED state is set through evdev interface, than asynchronous nature of USB transfer callback can lead to change of order of events echoed back to userland as it causes LED events to be echoed with some lag. Fix that with echoing of LED events synchronously in ioctl handler.
