spi: omap2-mcspi: remove several redundant variables
Variable count, l, mcspi and spi_cntrl are being assigned but are never used hence they are redundant and can be removed. Cleans up clang warnings: warning: variable 'count' set but not used [-Wunused-but-set-variable] warning: variable 'l' set but not used [-Wunused-but-set-variable] warning: variable 'mcspi' set but not used [-Wunused-but-set-variable] warning: variable 'spi_cntrl' set but not used [-Wunused-but-set-variable] Signed-off-by: Colin Ian King <colin.king@canonical.com> Signed-off-by: Mark Brown <broonie@kernel.org>
