From faafd6ca7e6e7100d21d3f43ec17674f36c9f843 Mon Sep 17 00:00:00 2001 From: Sumit Gupta Date: Wed, 21 Jun 2023 19:14:00 +0530 Subject: memory: tegra: make icc_set_bw return zero if BWMGR not supported Return zero from icc_set_bw() to MC client driver if MRQ_BWMGR_INT is not supported by the BPMP-FW. Currently, 'EINVAL' is returned which causes error message in client drivers even when the platform doesn't support scaling.
