Subject: [PATCH v2 2/2] staging: r8188eu: correct error logic of _rtw_init_recv_priv()
Date:   Sun,  5 Feb 2023 09:05:59 +0100
Message-Id: <20230205080559.8319-3-straube.linux@gmail.com>
In-Reply-To: <20230205080559.8319-1-straube.linux@gmail.com>

Precedence: bulk

Convert the function _rtw_init_recv_priv() away from returning _FAIL
and _SUCCESS, which uses inverted error logic. Return 0 for success
and negative values for failure instead.

v2:
Removed the initialization of the variable err since it's not needed.
