There may be spi devices that do not require a register read mask to read the registers. Currently the code sets the read mask based on a non-zero value passed in from the driver or if that value is 0 sets the read mask to 0x80.
It only sets it to the bus default if both read_flag_mask and write_flag_mask are 0. The assumption is that both of them being zero is a invalid configuration and either of them (or both) have to be non-zero for proper operation, since otherwise the device can't tell the difference between a read and a write.
Do you have a device where both the read and the write mask is 0? - Lars -- To unsubscribe from this list: send the line "unsubscribe linux-omap" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
