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@xxxxxx> --- Changes in v3: - add dytc_profile_cycle function Changes in v2: - only switch platform profiles if supported, otherwise keep the behavior.
