Message-Id: <20221126160129.178697-10-martin@kaiser.cx> Date: Sat, 26 Nov 2022 17:01:28 +0100 From: Martin Kaiser <martin@...ser.cx> To: Greg Kroah-Hartman <gregkh@...uxfoundation.org> Cc: Larry Finger <Larry.Finger@...inger.net>, Phillip Potter <phil@...lpotter.co.uk>, Michael Straube <straube.linux@...il.com>, Pavel Skripkin <paskripkin@...il.com>, linux-staging@...ts.linux.dev, linux-kernel@...r.kernel.org, Martin Kaiser <martin@...ser.cx> Subject: [PATCH 09/10] staging: r8188eu: simplify error handling for missing station Simplify the code to handle the case where we're associated to a station that is not in our list of known stations. We can simply exit in this case. This patch reverts the if-condition and saves one level of indentation.
