kernel patch - dvbsky s960

[geronimobb]

Hy,

I don't know if this is the right place to ask for, but asking doens't hurt...

There is allready a longer time (months) a problem with the dvbsky s960 satellite tuner under linux. I use a container under proxmox to utilize these tuners (tvheadend). There is a patch available since a few weeks:
https://bugzilla.kernel.org/show_bug.cgi?id=199323
Could this patch be included with the next kernel upgrade in proxmox?

Kind regards.

The status of the bug is still 'new', so it could still take some time before the patch will be included somewhere..

Just to inform other interested people, i've compiled the proxmox kernel with this patch, and the patch seems to solve the issues (some days allready).

I can also confirm the patch works for me.
Running Proxmox VE 6.0, compiled custom kernel at version 5.0.21-1-pve

Steps for beginners like myself:
SSH to Proxmox
# apt install automake cpio dh-python file gcc kmod libiberty-dev libpve-common-perl libtool perl-modules python-minimal sed tar zlib1g-dev libslang2-dev
# cd /usr/src
# git clone git://git.proxmox.com/git/pve-kernel.git
# cd pve-kernel
# nano patches/kernel/dvbsky.patch
