[ Upstream commit00a72db718] On an IRQ handler we should not return normal error codes as 'irqreturn_t' is expected. This is done by jumping to the 'check_burst32' label where we return 'IRQ_HANDLED'. Note that it is fine to do the burst32 check in this error path. If we have proper settings to apply burst32, we might just do the setup now so that the next sample already uses it.

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.
