[BUG] Keyboard may randomly break on Lenovo Yoga 7 14IAL7

[rcky844]

Problem Description When the module is probed at startup, issues may arise where the keyboard is broken beyond usability (e.g. letters type out as uppercase variants, enter key does not work). At other times, when this doesn't happen, certain keys handled by ideapad_laptop kernel module may not function (e.g. favorites key).

I know that this kernel module wasn't intended for my laptop. One, the name itself implies it's for Lenovo Legion laptop, and two, the comment blocks in the kernel module itself describes the 16" variant of my laptop, which has two fans instead of one, as well as a dedicated GPU. I wonder if it is some sort of resource conflicts. However, modprobing the module after the ideapad_laptop kernel module (or after bootup) seems to solve my issue of some keys not working on the more normal boots, but the issue where the whole keyboard is broken isn't fix and will come up every so often.

Please note that my laptop is also on a prototype version of BIOS, and the following modprobe.d config is used:

options legion_laptop enable_platformprofile=0
softdep legion_laptop pre: ideapad_laptop

Note that platform profile appears to be handled by another mainlined kernel module.
