Applied patch platform/100-PCI-mt7621-Add-MediaTek-MT7621-PCIe-host-controller-.patch (forced; needs refresh)
Upon inspecting drivers/staging/mt7621-pci/pci-mt7621.c.rej, it seems that
the original patch wants to delete drivers/staging/mt7621-pci/pci-mt7621.c
but upstream's version was not an exact match. I opted to delete that
file.
5. Suggestion by hauke: 19098934f9
"This patch is in upstream kernel, but it was backported to the old
staging driver in kernel 5.15."

Subject: [PATCH] mtd: allow getting MTD device associated with a specific DT
|
|
node
|
|
MIME-Version: 1.0
|
|
Content-Type: text/plain; charset=UTF-8
|
|
Content-Transfer-Encoding: 8bit
|
|
|
|
MTD subsystem API allows interacting with MTD devices (e.g. reading,
|
|
writing, handling bad blocks). So far a random driver could get MTD
|
|
device only by its name (get_mtd_device_nm()). This change allows
|
|
getting them also by a DT node.
|
|
|
|
This API is required for drivers handling DT defined MTD partitions in a
|
|
specific way (e.g. U-Boot (sub)partition with environment variables).
