Subject[PATCH AUTOSEL 5.5 500/542] i2c: cros-ec-tunnel: Fix slave device enumeration
Date
From: Akshu Agrawal <akshu.agrawal@amd.com>

[ Upstream commit 8ff2d7ca4a55dfabf12e876369835bd024eb4621 ]

During adding of the adapter the slave device registration
use to fail as the acpi companion field was not populated.
