The controller occasionally doesn't respond to subcommands. It appears that it's dropping them. To improve reliability, this patch attempts one retry in the case of a synchronous send timeout. In testing, this has resolved all timeout failures (most common for LED setting and rumble setting subcommands). The 1 second timeout is excessively long for rumble and LED subcommands, so the timeout has been made a param for joycon_hid_send_sync. Most subcommands continue to use the 1s timeout, since they can result in long response times. Rumble and LED setting subcommands have been reduced to 250ms, since response times for them are much quicker (and this significantly reduces the observable impact in the case of a retry being required).

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.
