[PATCH 0/3] rtlwifi: Fix some errors in recent patches

[Larry Finger]

When formuating the patches that converted the GET_XXX macros that read
RX and TX descriptor values, I made all of them return "int" values,
Unfortunately, the resulting inline routines must return unsigned values
when all 32-bits are returned as these entities are frequently addresses.

Although I have submitted fixes for several drivers, only 3 are affected
as the problem caused failures that led me to the problem.

Fortunately, none of these faulty changes will reach mainline until 5.4,
thus most users will not be affected until 5.4-rc1.

[PATCH 1/3] rtlwifi: rtl8821ae: Fix incorrect returned values

[Larry Finger]

In commit bd421dab7515 ("rtlwifi: rtl8821ae: Convert macros that set
descriptor"), all the routines that get fields from a descriptor
were changed to return signed integer values. This is incorrect for the
routines that get the entire 32-bit word. In this case, an unsigned
quantity is required.
