The patch titled
spi: spi_s3c24xx must initialize num_chipselect
has been removed from the -mm tree. Its filename was
spi-spi_s3c24xx-must-initialize-num_chipselect.patch
This patch was dropped because it was merged into mainline or a subsystem tree

------------------------------------------------------
Subject: spi: spi_s3c24xx must initialize num_chipselect
From: Ben Dooks <ben-linux@xxxxxxxxx>
The SPI core now expects num_chipselect to be set correctly as due to added
checks on the chip being selected before an transfer is allowed. This patch
adds a num_cs field to the platform data which needs to be set correctly
before adding the SPI platform device.
