Subject: staging: kpc2000: kpc_spi: remove function kp_spi_bytes_per_word()
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=1914e9ebd362af679a4bf384e7960d47788d27e1;p=linux.git

staging: kpc2000: kpc_spi: remove function kp_spi_bytes_per_word()

The static function kp_spi_bytes_per_word() is defined in kpc2000_spi.c,
but it is completely unused. As this function is unused, it can and
should be removed.
