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. Signed-off-by: Kevin Darbyshire-Bryant <kevin@darbyshire-bryant.me.uk> [update from 4.4.68 to 4.4.69] Signed-off-by: Hauke Mehrtens <hauke@hauke-m.de>
