Subject: [PATCH] dma-debug: fix debugfs initialization order
Date:   Thu, 22 Jul 2021 11:18:18 +0200

Due to link order, dma_debug_init is called before debugfs has a chance
to initialize (via debugfs_init which also happens in the core initcall
stage), so the directories for dma-debug are never created.

Move the dma_debug_init initcall from core to postcore stage so that
debugfs will already be initialized by the time this is called, making
it oblivious to link-ordering.

Fixes: 15b28bbcd567 ("dma-debug: move initialization to common code")
