You are making a new patch versions (v5) against your previous one. This is 
not how the development process works...

Make v6 against a clean staging tree, and change your commit message 
accordingly:

Rename tmpVal to avg_val in process_link_qual() to reflect the intended use of 
the variable and conform to the kernel coding style. 

Not directly related but, there is no need to say that process_link_qual() is 
a function (parentheses already say that). Furthermore, by renaming you make 
it clear what is the intended use of symbols, you don't "give meaning" to them 
(they already have meaning by the mere fact that they serve their intended 
purpose - https://ludwig.guru/s/to+give+meaning+to+something).

Remember that only the final versions of patches, the accepted version, will be 
applied against the kernel. Therefore, if this version was good, it couldn't 
be applied because in process_link_qual() there is no variable called pct_val.

git-am on your patch gives expected errors:

Applying: staging: rtl8712: rename tmpVal to avg_val
error: patch failed: drivers/staging/rtl8712/rtl8712_recv.c:861
error: drivers/staging/rtl8712/rtl8712_recv.c: patch does not apply

As said, a clean process_link_qual() has no pct_val variable.
