Sorry to lead to this issue,
This too has been going on since -rc1, but it's not obvious what caused it.
At a guess, looking around the amba changes, I'm assuming it's
7719a68b2fa4 ("ARM: 9192/1: amba: fix memory leak in amba_device_try_add()")
Does reverting that commit make it go away?
There may be a patch that solves that, but it's never been submitted to
my patch system:
https://lore.kernel.org/all/20220524025139.40212-1-wangkefeng.wang@xxxxxxxxxx/
This patch is to fix the above issue reported-by Guenter, and it merged
into linux-next
for a while, which Applied in
https://www.armlinux.org.uk/developer/patches/viewpatch.php?id=9207/1
I'm sorry, but I'm utterly crap at picking up patches off mailing lists,
so if stuff doesn't end up inthe patch system, it gets missed.
Is there some special for bugfix patch when send to arm patch system, please
let me know if I missed.
