As only the hardware access functions up til and including mv88e6xxx_g1_atu_mac_read() called under the interrupt handler need to take the chip lock, we release the chip lock after this call. The follow up code that handles the violations can run without the chip lock held. In further patches, the violation handler function will even be incompatible with having the chip lock held. This due to an AB/BA ordering inversion with rtnl_lock(). Signed-off-by: Hans J.

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.
