I'll check this patch tomorrow, when I get back home.
In the meantime some style related comments below.

Please don't the comments to the chipset revision definitions. These macros are usually used all over the place; there is no need to specify this here.

With respect to the comment change: are you sure this is only about RX antenna diversity?
Also, I'm wondering if the change to the if condition brings us everything that is wanted. Checking the same chipset for different minimal revisions doesn't make a whole lot of sense to me.
Sure, you are fixing later RT5370 revisions here, but may be botching up early RT5390 revisions here at the same time

The same comment on the if conditions apply here.
