| |
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]
