After reviewing your patch I agree with your findings!
So thank you very much for bringing this up and sending a fix

The subject of this patch does not match what we usually have
Can you please make it start with "spi: meson-spicc:" (see git log
drivers/spi/spi-meson-spicc.c)

I'd prefer this part to go into a separate patch so that separate
patch can get the following Fixes tag (which should then be added
above your Signed-off-by):
Fixes: 3e0cf4d3fc29 ("spi: meson-spicc: add a linear clock divider support")

The remaining changes (to my understanding) should get:
Fixes: 454fa271bc4e ("spi: Add Meson SPICC driver")

The "Fixes" tag is relevant so bug-fixes can be backported to older
kernel versions automatically.

So it would be great if you could send a second version with the above
changes considered.


Thank you and best regards,
Martin
