Colin Ian King c0f2c063ab net: hp100: fix always-true check for link up state
[ Upstream commit a7f38002fb69b44f8fc622ecb838665d0b8666af ]

The operation ~(p100_inb(VG_LAN_CFG_1) & HP100_LINK_UP) returns a value
that is always non-zero and hence the wait for the link to drop always
terminates prematurely.  Fix this by using a logical not operator instead
of a bitwise complement.  This issue has been in the driver since
pre-2.6.12-rc2.

Detected by CoverityScan, CID#114157 ("Logical vs. bitwise operator")

Linux kernel
============

This file was moved to Documentation/admin-guide/README.rst

Please notice that there are several guides for kernel developers and users.
These guides can be rendered in a number of formats, like HTML and PDF.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.

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.
