From 745649c59a0d1fde9dcc02286f23f8c78a1f724d Mon Sep 17 00:00:00 2001 From: Colin Ian King Date: Wed, 18 Aug 2021 15:10:51 +0100 Subject: spi: rockchip-sfc: Fix assigned but never used return error codes Currently there are two places where the error return variable ret is being assigned -ETIMEDOUT on timeout errors and this value is not being returned. Fix this by returning -ETIMEDOUT rather than redundantly assiging it to ret.
