From b5c203ea0b961ac4b34268e2023496fec60745d4 Mon Sep 17 00:00:00 2001 From: Sudeep Holla Date: Fri, 29 Apr 2022 12:39:43 +0100 Subject: [PATCH] firmware: arm_ffa: Fix uuid parameter to ffa_partition_probe [ Upstream commit f3c45c045e25ed52461829d2ce07954f72b6ad15 ] While we pass uuid_null intentionally to ffa_partition_probe in ffa_setup_partitions to get the count of the partitions, it must not be uuid_null in ffa_partition_info_get which is used by the ffa_drivers to fetch the specific partition info passing the UUID of the partition. Fix ffa_partition_info_get by passing the received uuid down to ffa_partition_probe so that the correct partition information is fetched.
