Hi Greg and Sasha,
Please apply commit bc7f2cd7559c ("spi: bcm2835: remove use of
uninitialized gpio flags variable") as a fix to commit
5e31ba0c0543 ("spi: bcm2835: fix gpio cs level inversion"), which
appears to be in 5.4 and 5.9 at the time of writing this. I did not try
to apply it but I did not see an outstanding failure email about it. If
it does not apply cleanly, let me know.
Cheers,
Nathan
