Prasanna S 9bb6ec4e32 serial: qcom-geni: fix UART_RX_PAR_EN bit position 
[ Upstream commit ca2584d841 ]

UART_RX_PAR_EN is incorrectly defined as bit 3, which triggers false
framing errors (S_GP_IRQ_1_EN) and causes received data to be dropped
when parity is enabled and the parity bit is 0.

Define UART_RX_PAR_EN as bit 4 of the SE_UART_RX_TRANS_CFG register, as
specified in the reference manual.

README 

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.
