Similar to the 4.9 series, I looked at xilinx-4.19 from https://github.com/Xilinx/linux-xlnx/tree/xlnx_rebase_v4.19 for possible backports to LTS kernels These are the ones that look like they should be in the 4.19 lts tree: d86c5a676e5b ("usb: dwc3: gadget: always try to prepare on started_list first") 60208a267208 ("mmc: sdhci-of-arasan: Do now show error message in case of deffered probe")

check for SKBTX_HW_TSTAMP") Whereas these are harmless but probably not helpful: 77ec669f257b ("serial: uartps: Do not initialize field to zero again") ea42d7a67a9e ("tty: serial: uartlite: Enable
