Subject: cxl/pci: Consolidate wait_for_media() and wait_for_media_ready()
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=1e14c9fbb55fbc48eb88b55d1736c994b1deb631;p=linux.git

cxl/pci: Consolidate wait_for_media() and wait_for_media_ready()

Now that wait_for_media() does nothing supplemental to
wait_for_media_ready() just promote wait_for_media_ready() to a common
helper and drop wait_for_media().
