Alexander Stein 283fdc5cfb i2c: imx-lpi2c: check only for enabled interrupt flags
[ Upstream commit 1c7885004567e8951d65a983be095f254dd20bef ]

When reading from I2C, the Tx watermark is set to 0. Unfortunately the
TDF (transmit data flag) is enabled when Tx FIFO entries is equal or less
than watermark. So it is set in every case, hence the reset default of 1.
This results in the MSR_RDF _and_ MSR_TDF flags to be set thus trying
to send Tx data on a read message.
Mask the IRQ status to filter for wanted flags only.

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.
