mainlining shenanigans
2ff23c4802
When receiving data on RX pin before ->uart_startup() is called, some error bits in the state register could be set up (like BRK_DET). This is harmless when using only the standard UART (error bits are read-only), but may procude an endless loop once in the extended UART RX interrupt handler (error bits must be cleared). Clear the status register in ->uart_startup() to avoid this situation.

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.
