Subject: x86: ich-spi: Remove useless assignment in ich_spi_xfer()
X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=52dd56ba847acd048205e6412e779fda991c95d3;p=u-boot.git

x86: ich-spi: Remove useless assignment in ich_spi_xfer()

In ich_spi_xfer() when the driver presets control fields, control
variable gets assigned twice. Apparently only the last assignment
takes effect. Remove the other one.
