This is what confuses me:
--- git-log output ---
commit 8a893759d0075ea9556abcf86a4826d9865ba4bf (origin/staging-testing)
Author: Phillip Potter <phil@xxxxxxxxxxxxxxxx>
Date: Sat Nov 6 23:16:36 2021 +0000
staging: r8188eu: remove MSG_88E macro
--- end of git-log output ---
Aside from the "Date" field, I know that this patch has been sent to the list
during the last night and that it goes to the same branch (staging-testing)
to which my patch should go. I know I'm still missing something, but I cannot
understand what it is... :(
Anyway, never mind. I don't want to bother you with this silly questions :)
Again, thanks,
Fabio
