Subject: [PATCH RFC] platform/x86: Lenovo sub directory
Looking for feedback if this is a good idea or not, and if I've missed
anything important.
Over the holidays it was raining and I was bored so I was toying with the
idea of moving some of the thinkpad_acpi functionality out of the file
into their own modules - the file is a bit of a beast. I'd like to try and
get any commonality between thinkpad, ideapad, etc where possible.
My plan was to first look at pulling out the platform_profile pieces and
then extend to other pieces (fans, temp, sensors, etc).
Doing this will, potentially, create a number of lenovo_xxx files and so it
seemed nice to put lenovo stuff in it's own subdirectory (in a similar way
to other vendors) before starting the exercise.
This was my attempt to see if it was easy - and it was.
Please let me know:
1) Is this OK to do, or does it cause any problems?
2) Have I missed anything important?
3) I don't want to tread on any toes - so if there is protocol to follow
with moving files please let me know :) (Or a preferred way to do such an
exercise)
4) I don't have any ideapads to test with. I think this is low risk, but
if anybody is able to confirm nothing breaks please let me know.
I will see if I can scrounge some HW from somewhere in the meantime.
I will need to rebase before proposing this officially, so please ignore
the fact that this is based off 6.7-rc1 and therefore a bit out of date.
