Subject: [PATCH 4/6] staging: kpc2000: kpc_spi: remove unnecessary struct member chip_select
Date:   Wed,  5 Jun 2019 01:09:11 +0000

The structure kp_spi_controller_state, defined in the kpc2000_spi
driver, contains a member named chip_select which is never used after
initialization. Therefore, it should be removed for simplicity's sake.
