Rename variables
* TM_trigger to tm_trigger
* TxPowerCheckCnt to txpower_check_count
to avoid CamelCase which is not accepted by checkpatch.pl .

While this is nice overall, I think you just found a bug in the driver.
Why is this a static variable? That means this affects all devices that
this driver touches, which seems very wrong, right?
So shouldn't tm_trigger be a per-device attribute?

It also should be a boolean, right?
Can you fix this up to be a per-device attribute instead?
thanks,

Yes, it should a boolean, But in the mainline, the maintainers have kept it u8 for some reason [1].
So I am not sure if it should be boolean. Please let me know your
thoughts on this.
> Can you fix this up to be a per-device attribute instead?
Sure, just to make sure that we are on the same page, you are expecting
a patch similar to this [2] right?
Since I am new to mainline kernel development, I wanted to ensure that I am on the right track.
Thanks
