Subject: spi: cadence: revert "Add SPI transfer delays"
From: Nam Cao <namcao@xxxxxxxxxxxxx>
commit 7a733e060bd20edb63b1f27f0b29cf9b184e0e8b upstream.
The commit 855a40cd8ccc ("spi: cadence: Add SPI transfer delays") adds a
delay after each transfer into the driver's transfer_one(). However,
the delay is already done in SPI core. So this commit unnecessarily
doubles the delay amount. Revert this commit.
