Subject: spi: omap2-mcspi: Fix the redifine warning
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=6a47d80308a824c32c47fbef6b8e8b59de08af94;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

spi: omap2-mcspi: Fix the redifine warning

Fix the below warning
drivers/spi/spi-omap2-mcspi.c:336:34: warning: symbol 'tx' shadows an earlier one
drivers/spi/spi-omap2-mcspi.c:327:12: originally declared here

So delete the u8 tx as it is assigned and not used(resigned afterwards).
