From 4f22b8954b13f6a75d57498b49084fc409257c61 Mon Sep 17 00:00:00 2001 From: "Tobin C. Harding" Date: Wed, 12 Apr 2017 09:56:50 +1000 Subject: [PATCH] staging: ks7010: remove unused spin_lock Driver SDIO private data structure description includes a spin_lock that is never used. This data structure only contains a pointer to the sdio_func and a pointer to the main device private data. A spin_lock is not required here. Remove unused spin_lock. Signed-off-by: Tobin C.
