Petr Machata 89e602ee6e mlxsw: spectrum: PTP: Disable BH when working with PHC
Up until now, the PTP hardware clock code was only invoked in the process
context (SYS_clock_adjtime -> do_clock_adjtime -> k_clock::clock_adj ->
pc_clock_adjtime -> posix_clock_operations::clock_adjtime ->
ptp_clock_info::adjtime -> mlxsw_spectrum).

In order to enable HW timestamping, which is tied into trap handling, it
will be necessary to take the clock lock from the PCI queue handler
tasklets as well.

Therefore use the _bh variants when handling the clock lock. Incidentally,
Documentation/ptp/ptp.txt recommends _irqsave variants, but that's
unnecessarily strong for our needs.

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.
