From a62cb5693b93a4bec3d4c0ae072d9622d6a5ea0f Mon Sep 17 00:00:00 2001 From: Tim Wawrzynczak Date: Wed, 8 Dec 2021 21:16:43 -0700 Subject: [PATCH] device: Make pciexp_get_ltr_max_latencies a public function Some device drivers may need to get access to the LTR values for their respective devices, therefore export this function instead of marking it static.
