[PATCH 08/14] Input: adxl34x - fix gcc-7 -Wint-in-bool-context warning

[Arnd Bergmann]

FIFO_MODE is an 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]

This converts the test to an explicit comparison with zero,
making it clearer to gcc and the reader what is intended.
