This enables relocating source and build trees to different roots,
provided they stay reachable relative to one another.  Useful for
builds done within a sandbox where the eventual root is prefixed
by some undesirable path component.
kube-proxy won't enable ipvs unless it can modprobe nf_conntrack_ipv4 and
find it in the list of loaded modules afterward.  Thus an alias isn't
enough to maintain compatibility; we need an actual module.

[ Upstream commit c0fd99d ]

Writing to the built-in strings arrays doesn't work if driver is loaded
as kernel module. This is also considered as a bad pattern. Fix this by
adding a call to clk_get() with legacy clock name. This fixes following
kernel oops if driver is loaded as module:
