From: Nicolas Saenz Julienne Date: Thu, 7 May 2020 17:20:20 +0000 (+0200) Subject: PCI: brcmstb: Assert fundamental reset on initialization X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=22e21e51ce755399fd42055a3f668ee4af370881;p=linux.git PCI: brcmstb: Assert fundamental reset on initialization While preparing the driver for upstream this detail was missed. If not asserted during the initialization process, devices connected on the bus will not be made aware of the internal reset happening. This, potentially resulting in unexpected behavior.
