Arnd Bergmann 1dbc080c9e Input: adxl34x - do not treat FIFO_MODE() as boolean ...

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.
