Doesn't seem to apply to wireless-drivers (which I fast forwarded to
v4.20-rc1 today):
Failed to apply the patch: ['git', 'am', '-s', '-3'] failed: 128
fatal: sha1 information is lacking or useless (drivers/net/wireless/mediatek/mt76/mt76x2/pci_init.c).
error: could not build fake ancestor
So please rebase and resend.
