Hi, I apologize for the delay. I recently saw Carlos's patch and your reviews, so I improved my driver according to it and made it ready for another version. I didn't include the documentation for the new zoned keyboard backlight naming since Carlos is going to do that. However, I changed the naming of corner led because it isn't affected when other zones' brightness changes. And one last reason to not name it kbd_zoned_backlight is the fact that it isn't on the keyboard, it's on the two corners of the laptop. I'm still not sure how to name it, so I named it 'backlight'. Here's a photo of the laptop: https://imgur.com/a/JEqMiGL Mustafa Ekşi (1): platform/x86: Add wmi driver for Casper Excalibur laptops MAINTAINERS | 6 + drivers/platform/x86/Kconfig | 14 + drivers/platform/x86/Makefile | 1 + drivers/platform/x86/casper-wmi.c | 656 ++++++++++++++++++++++++++++++ 4 files changed, 677 insertions(+) create mode 100644 drivers/platform/x86/casper-wmi.c -- 2.45.2
