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. Signed-off-by: Geordan Neukum <gneukum1@gmail.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
