[PATCH 1/3] iio: health: afe440x: Remove code in comments

[simran singhal]

In commit message I am clearly saying commenting out the code is a bad Idea.
As comments are for explaining what code is about.
And that's what I am doing in the patch deleting the commented codes.

My subject also says "Remove code in comments"

Than what is not matching?

Read your own patch.

You are removing #defines not comments.

If the whole thing is in comments, then
the #defines immediately above what you
are removing should also be deleted.

[PATCH 2/3] iio: health: afe4404: Remove all unused functions

[simran singhal]

The functions afe440x_show_register and afe440x_store_register are never
used anywhere in the kernel. So, remove their definitions.
Grepped to find occurences.

[SIMRAN SINGHAL]

Please ignore this Patch. As this patch is completely wrong due to
my lack of understanding.
