[PATCH 2/8] accel/habanalabs: use device-name directory in debugfs-driver-habanalabs

From: Ofir Bitton
Date: Mon May 27 2024 - 11:18:50 EST


From: Tomer Tayar <ttayar@xxxxxxxxx>

The device debugfs directory was modified to be named as the parent
device name.
Update the description of 'mmu' and 'mmu_error' to use the new path.
