From: Vincent Stehlé Date: Sat, 15 Oct 2016 16:51:55 +0000 (+0200) Subject: configs/lego_ev3: bump kernel to 4.4 series X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=46a373e2f59356f70a551507b7b8dc2943fe49ff;p=buildroot.git configs/lego_ev3: bump kernel to 4.4 series Bump kernel revision used by lego_ev3_defconfig to the latest tag from ev3dev, as suggested by Peter. This is a 4.4 series kernel, which has the added benefit of not necessitating a specific gcc to boot. We need a patch to create an empty drivers/lego/Kconfig file for the build to succeed though, as the ev3dev kernel normally expects a drivers tree to be checked out there.
