I took a look, but it's pretty complex.  You could take the code and
reorganize it so that it is more readable, and then take the definition of
the ARRAY_SIZE macro, to better see what is going on.

Hello Greg, Julia,
I was able to successfully build the fbtft object file for arm architecture as
well. I used gcc 6.5.0 and 9.5.0 tool chains. It was successful using both. I
have attached the build log from my machine for your reference.

I am also looking at the .i file and rearrange the expanded macro to understand
it. However, since it is built successfully, I am not sure if that is truly the
problem area.

Should I resend the patch and check if it still errors the kernel build bot?
Anything else I can try?

Looks like the change I proposed is causing nesting inside the write_reg
function due to additional set of { & } brackets for the __VA_ARGS__ symbol.

Am I understanding it right?

Hello Julia, Greg,
I am unable to reproduce this build failure on my local machine. I tried the X86
and arm based build. I am unable to troubleshoot this further. Do you have any
other suggestions? If not, I will drop this patch from my watch list.

Thank you,
./drv
