Subject: [PATCH] wifi: rtl8xxxu: fixing IQK failures for rtl8192eu
Fixing "Path A RX IQK failed" and "Path B RX IQK failed"
issues for rtl8192eu chips by replacing the arguments with
the ones in the updated official driver.
I think it would be better if you can point out which version you use, and
people will not modify them back to old version suddenly.

I think this is a test code of vendor driver. No need them here.

I have compared your patch with internal code, and they are the same.
But, I don't have a test.
