Andrey, can you fix this? I don't have SPI hardware and wouldn't be able to check the functionality after the fixes. However, some things are obvious, e.g. u16 reg_out = cpu_to_le16(reg | IF_SPI_WRITE_OPERATION_MASK); should either be reg_out = reg | IF_SPI_WRITE_OPERATION_MASK; or __le16 reg_out = cpu_to_le16(reg | IF_SPI_WRITE_OPERATION_MASK); Here's a run with sparse: $ make -C /usr/src/linux-wl/ modules SUBDIRS=drivers/net/wireless/libertas C=2 CF=-D__CHECK_ENDIAN__
