From b2d110cd5d28ded813f060b735cd68bfe2e5010f Mon Sep 17 00:00:00 2001 From: Johan Hovold Date: Mon, 6 Mar 2023 08:56:51 +0100 Subject: interconnect: drop unused icc_link_destroy() interface Now that the link array is deallocated when destroying nodes and the explicit link removal has been dropped from the exynos driver there are no further users of and no need for the icc_link_destroy() interface.
