How about one patch per variable that is being removed as this was fine,
but others below are not ok.

Shall I describe that some of these became unused
after DBG_871X removal?

yes, actually, not just the ">>" marked ones, but also
all others reported in automatic email.
Shall I limit to the marked ones?
Should I put in In-Reply-To the test robot email?
Or just the output of the test robot in the changelog?

* [PATCH] staging: rtl8723bs: remove unused variables

A cleanup patch removed the only user of two local variables:
drivers/staging/rtl8723bs/hal/hal_btcoex.c: In function 'hal_btcoex_Initialize':
drivers/staging/rtl8723bs/hal/hal_btcoex.c:1415:5: error: unused variable 'ret2' [-Werror=unused-variable]
drivers/staging/rtl8723bs/hal/hal_btcoex.c:1414:5: error: unused variable 'ret1' [-Werror=unused-variable]
This removes the declarations as well.
Fixes: 95b3b4238581 ("staging: rtl8723bs: remove ternary operators in assignmet statments")
