From 8334e04d24462b6fa3b53c77442a21f473149a1d Mon Sep 17 00:00:00 2001 From: Hauke Mehrtens Date: Sat, 29 Feb 2020 16:49:09 +0100 Subject: [PATCH] gemini: Remove kernel 4.14 support This target was switched to kernel 4.19 more than 6 months ago in commit f342ffd300da ("treewide: kernel: bump some targets to 4.19") and now with kernel 5.4 support being added it gets harder to support kernel 4.14 in addition to kernel 4.19 and 5.4.
