If some bits were cleared by i2c_dw_read_clear_intrbits_slave() in i2c_dw_isr_slave() and not handled immediately, those cleared bits would not be shown again by later i2c_dw_read_clear_intrbits_slave(). They therefore were forgotten to be handled. i2c_dw_read_clear_intrbits_slave() should be called once in an ISR and take its returned state for all later handlings.

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.
