[PATCH 6.6 084/158] PCI: Simplify pcie_capability_clear_and_set_word() to ..._clear_word()

[Greg Kroah-Hartman <gregkh@linuxfoundation.org>]

6.6-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Ilpo Järvinen <ilpo.jarvinen@linux.intel.com>

[ Upstream commit 0fce6e5c87faec2c8bf28d2abc8cb595f4e244b6 ]

When using pcie_capability_clear_and_set_word() but not actually *setting*
anything, use pcie_capability_clear_word() instead.
