checkpatch gives a warning on this patch:
WARNING: From:/Signed-off-by: email name mismatch: 'From: "Tim van der Staaij | Zign" <Tim.vanderstaaij@zigngroup.com>' != 'Signed-off-by: Tim van der Staaij <tim.vanderstaaij@zigngroup.com>'
Should it contain a Fixes tag so that it can be backported to older stable-kernels?
