Claudiu Beznea f1131b9c23 net: phy: micrel: use kszphy_suspend()/kszphy_resume for irq aware devices 
On a setup with KSZ9131 and MACB drivers it happens on suspend path, from
time to time, that the PHY interrupt arrives after PHY and MACB were
suspended (PHY via genphy_suspend(), MACB via macb_suspend()). In this
case the phy_read() at the beginning of kszphy_handle_interrupt() will
fail (as MACB driver is suspended at this time) leading to phy_error()
being called and a stack trace being displayed on console. To solve this
.suspend/.resume functions for all KSZ devices implementing
.handle_interrupt were replaced with kszphy_suspend()/kszphy_resume()
which disable/enable interrupt before/after calling
genphy_suspend()/genphy_resume().

The fix has been adapted for all KSZ devices which implements
.handle_interrupt but it has been tested only on KSZ9131.

Fixes: 59ca4e58b9 ("net: phy: micrel: implement generic .handle_interrupt() callback")

README 

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.
