Linux 5.11.2

Linux 5.11.2

[Greg Kroah-Hartman]

I'm announcing the release of the 5.11.2 kernel.

All users of the 5.11 kernel series must upgrade.

The updated 5.11.y git tree can be found at:
	git://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable.git linux-5.11.y
and can be browsed at the normal kernel.org git web browser:
	https://git.kernel.org/?p=linux/kernel/git/stable/linux-stable.git;a=summary

thanks,

greg k-h

Hi,

thanks for the upgrade.
There seems to be a dangling link in the git repository:
`scripts/dtc/include-prefixes/c6x`

Jörg.

Introduced in 5.11.2.

IMO, it would be this commit:
commit a579fcfa8e49cc77ad59211bb18bc5004133e6a0
Author: Arnd Bergmann <arnd@arndb.de>
Date:   Mon Jan 18 12:45:46 2021 +0100

     c6x: remove architecture

targetting 5.12-rc1. So unrelated to 5.11.2 at all, right?

thanks,
