Subject: [PATCH v2 12/13] staging: r8188eu: rtw_action_public_decache's token is a u8
Date:   Sun, 30 Oct 2022 18:33:25 +0100
Message-Id: <20221030173326.1588647-13-martin@kaiser.cx>
In-Reply-To: <20221030173326.1588647-1-martin@kaiser.cx>

MIME-Version: 1.0
Content-Transfer-Encoding: 8bit
Precedence: bulk

Both callers of rtw_action_public_decache pass a u8 value for the token
parameter. We can change token from s32 to u8 and remove the code for
token < 0.
