All preceding patches do not touch spi-bcm2835.c,
that's what I meant with "front of the series".

I based the series on your for-5.4 branch and didn't notice that you had
already applied this one to for-5.3.  This wasn't really meant as a fix
and it's not necessary for it to to be applied to for-5.3, though there's
no harm either as long as it lands in Linus' tree before the other
patches in this series.

There is no difference aside from a Tested-by tag for Noralf Trønnes
which is missing from the commit on your for-5.3 branch.

Thanks,
