Pressing a button on a remote control unit will typically lead to messages being sent several times per second until the button is released. Some remote control units indicate long key presses by sending special "repeat" messages, for which the protocol driver calls rc_repeat(). Other units repeat the same message over and over, which will be handled by calling rc_keydown(). The function rc_keydown() never set the LIRC "repeat" flag to distinguish repeated messages that were sent due to a long keypress, and messages sent due to repeated short keypresses. While a user-space program may implement special logic to distinguish long keypresses, it is much simpler to be able to rely on the flag. Commitde142c3241("media: lirc: implement reading scancode") would never set the LIRC_SCANCODE_FLAG_REPEAT flag. Commitb66218fddf("media: lirc: ensure lirc device receives nec repeats") fixed it up for rc_repeat() but not rc_keydown().

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
