I thought about it. It would make this module complicated, but something like this fits well in the platform_profile module. I will implement the cycle there in v4. Best regards, Gergo

Ideapad laptops have thermal management or performance mode switch key (Fn + Q). They report KEY_PROG4. If supported, cycle platform profiles instead. Tested on Yoga7 14ARB7. Signed-off-by: Gergo Koteles <soyer@irl.hu> --- Changes in v3: - add dytc_profile_cycle function Changes in v2: - only switch platform profiles if supported, otherwise keep the behavior.
