Subject: staging: brcm80211: cleaned up fullmac macro BRCMF_PM_RESUME_RETURN_ERROR
X-Git-Tag: Ubuntu-5.4-5.4.0-11.14~20466^2^2~670

staging: brcm80211: cleaned up fullmac macro BRCMF_PM_RESUME_RETURN_ERROR

Macros impacting the code flow are sort of frowned upon. No other macro's
in the source code impact the code flow. Replaced macro by function.
