Upstream commit 3e9efc3299 ("i2c: aspeed: Handle master/slave combined irq events
properly") reworked the interrupt handling and fixed a warning in the process:
drivers/i2c/busses/i2c-aspeed.c: In function 'aspeed_i2c_bus_irq':
drivers/i2c/busses/i2c-aspeed.c:567:1: error: label 'out' defined but not used [-Werror=unused-label]
The warning is still present in v4.19.8 and can be fixed either by applying
that original patch, or by adding a simple #ifdef.
Here, I choose the second simpler option as the original patch seems too
invasive for a stable backport.

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.
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.
