From 088e28772c504ad622ba909b0f6d2986910e7a97 Mon Sep 17 00:00:00 2001 From: Kevin Darbyshire-Bryant Date: Mon, 15 May 2017 15:03:47 +0100 Subject: kernel: update kernel 4.4 to version 4.4.69 Refresh patches. A number of patches have landed upstream & hence are no longer required locally: 062-[1-6]-MIPS-* series 042-0004-mtd-bcm47xxpart-fix-parsing-first-block Reintroduced lantiq/patches-4.4/0050-MIPS-Lantiq-Fix-cascaded-IRQ-setup as it was incorrectly included upstream thus dropped from LEDE. As it has now been reverted upstream it needs to be included again for LEDE. Run tested ar71xx Archer C7 v2 and lantiq.
