From f82ce45273d4d8173243f08b943c9c371385c105 Mon Sep 17 00:00:00 2001 From: Geordan Neukum Date: Sun, 26 May 2019 01:18:27 +0000 Subject: [PATCH] staging: kpc2000: kpc_i2c: Remove unused rw_sem In pi2c_probe, a rw_sem is initialized and stashed off in the i2c_device private runtime state struct. This rw_sem is never used after initialization. Remove the rw_sem and cleanup unneeded header inclusion.
