Hi,
I am trying to make a kernel patch on spidev.c to fix a known issue in linux
6.6. I have written the patch and I can see that it is applied in my build/tmp
files however it is not functioning on the image.
My patch method is to create a recipes-kernel/linux directory in a custom
layer, create a linux-libc-headers_6.6.bbappend file and create a /poky
directory for the patch files.
Here are what my patch files look like from meta-custom/recipes-kernel/linux:
poky/0004-spidev.patch

2 Local patch for spidev

Please can someone let me know if any part of my patch is incorrect?
