Subject: [PATCH v3 9/9] Revert "PCI: brcmstb: Wait for Raspberry Pi's firmware when present"
Date: Fri, 12 Jun 2020 19:13:33 +0200	[thread overview]
Message-ID: <20200612171334.26385-10-nsaenzjulienne@suse.de> (raw)
In-Reply-To: <20200612171334.26385-1-nsaenzjulienne@suse.de>

This reverts commit 44331189f9082c7e659697bbac1747db3def73e7.

Now that the VL805 init routine is run through a reset controller driver
the device dependencies are being taken care of by the device core. No
need to do it manually here.
