Subject: [PATCH v2 2/3] s390/pci: remove unused bus_next field from struct zpci_dev
Date: Thu, 22 Sep 2022 11:52:38 +0200 [thread overview]
Message-ID: <20220922095239.2115309-3-schnelle@linux.ibm.com> (raw)
In-Reply-To: <20220922095239.2115309-1-schnelle@linux.ibm.com>
This field was added in commit 44510d6fa0c0 ("s390/pci: Handling
multifunctions") but is an unused remnant of an earlier version where
the devices on the virtual bus were connected in a linked list instead
of a fixed 256 entry array of pointers.
It is also not used for the list of busses as that is threaded through
struct zpci_bus not through struct zpci_dev.
