Seemingly unneeded based on new upstream code so manually deleted: layerscape: 820-usb-0007-usb-dwc3-gadget-increase-timeout-value-for-send-ep-c.patch Manually merged: generic-hack: 251-sound_kconfig.patch All other modifications made by update_kernel.sh Build system: x86_64 Build-tested: ipq806x/R7800, ath79/generic, bcm27xx/bcm2711 Run-tested: ipq806x/R7800, lantiq/Easybox 904 xDSL No dmesg regressions, everything functional Signed-off-by: John Audia <graysky@archlinux.us> [add lantiq test report, minor commit message clarification] Signed-off-by: Adrian Schmutzler <freifunk@adrianschmutzler.de>
