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
and need some feedback.  Was that the correct course of action?

"This patch is in upstream kernel, but it was backported to the old
staging driver in kernel 5.15."

* oxnas: sata_oxnas: use ata_link_err

Kernel 5.15.86 has backported ("ata: libata: move ata_{port,link,dev}_dbg
to standard pr_XXX() macros") and this is now causing compilation errors
for oxnas SATA driver due to usage of ata_link_printk().

Upstream has migrated to using the appropriate
ata_link_{err, warn, notice, info} calls a while ago so its not affected.

Lets do the same for oxnas SATA driver and use ata_link_err() instead of
ata_link_printk().

Subject: kernel/3.1[02]: move MTD root device setup code to mtdcore
The current code only allows to automatically set
root device on MTD partitions. Move the code to MTD
core to allow to use it with all MTD devices.
