[PATCH] spi: spi-gpio: fix compilation warning on 64 bits systems

From: Maxime Ripard
Date: Thu Jan 31 2013 - 05:13:07 EST


SPI_GPIO_NO_MOSI and SPI_GPIO_NO_MISO flags are type casted to unsigned
long, yet, they are to be stored in an unsigned int field in the
spi_gpio_platform_data structure.

This leads to the following warning during compilation on 64 bits systems:
warning: large integer implicitly truncated to unsigned type [-Woverflow]
