Subject: [PATCH 5/5] staging: r8188eu: convert _rtw_init_sta_priv() to common error logic
Date:   Sun,  2 Oct 2022 09:48:27 +0200
Message-Id: <20221002074827.8566-6-straube.linux@gmail.com>

Convert the function _rtw_init_sta_priv() to common kernel error logic.
Return 0 on success and negative value on failure. This is part of
getting rid of returning _SUCCESS and _FAIL which uses inverted error
logic and is used all over the driver.
