commit d2ace81bf902a9f11d52e59e5d232d2255a0e353 upstream. When half-duplex RS485 communication is used, after RX is started, TX tasklet still needs to be scheduled tasklet. This avoids console freezing when more data is to be transmitted, if the serial communication is not closed.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
