Subject: [PATCH 3/4] staging: r8188eu: convert _rtw_init_xmit_priv() to common error logic
Date: Fri, 11 Nov 2022 09:37:32 +0100 [thread overview]
Message-ID: <20221111083733.3144-4-straube.linux@gmail.com> (raw)
In-Reply-To: <20221111083733.3144-1-straube.linux@gmail.com>
Convert the function _rtw_init_xmit_priv() away from returning _FAIL
or _SUCCESS which uses inverted error logic. Use the common error
logic instead. Return 0 for success and negative values for failure.
