PCI: Add SPDX GPL-2.0+ to replace GPL v2 or later boilerplate

2018-01-28T21:49:06+00:00

Add SPDX GPL-2.0+ to all PCI files that specified the GPL and allowed
either GPL version 2 or any later version.

Remove the boilerplate GPL version 2 or later language, relying on the
assertion in b24413180f56 ("License cleanup: add SPDX GPL-2.0 license
identifier to files with no license") that the SPDX identifier may be used
instead of the full boilerplate text.

PCI: shpchp: Enable bridge bus mastering if MSI is enabled

2017-08-02T21:54:50+00:00

An SHPC may generate MSIs to notify software about slot or controller
events (SHPC spec r1.0, sec 4.7).  A PCI device can only generate an MSI if
it has bus mastering enabled.

Enable bus mastering if the bridge contains an SHPC that uses MSI for event
notifications.

PCI: Merge multi-line quoted strings

2014-06-11T02:20:42+00:00

Merge quoted strings that are broken across lines into a single entity.
The compiler merges them anyway, but checkpatch complains about it, and
merging them makes it easier to grep for strings.

No functional change.

PCI: Fix whitespace, capitalization, and spelling errors

2013-11-14T18:28:18+00:00

Fix whitespace, capitalization, and spelling errors.  No functional change.
I know "busses" is not an error, but "buses" was more common, so I used it
consistently.
