Subject[PATCH v2] Input: adxl34x - fix gcc-7 -Wint-in-bool-context warning
Date
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 FIFO_BYPASS,
making it clearer to gcc and the reader what is intended.

Fixes: e27c729219ad ("Input: add driver for ADXL345/346 Digital Accelerometers")
