FIFO_MODE() is a macro expression with a '<<' operator, which gcc points out could be misread as a '<': drivers/input/misc/adxl34x.c: In function 'adxl34x_probe': drivers/input/misc/adxl34x.c:799:36: error: '<<' in boolean context, did you mean '<' ? [-Werror=int-in-bool-context] While utility of this warning is being disputed (Chief Penguin: "This warning is clearly pure garbage.") FIFO_MODE() extracts range of values, with 0 being FIFO_BYPASS, and not something that is logically boolean. This converts the test to an explicit comparison with FIFO_BYPASS, making it clearer to gcc and the reader what is intended.
