3.2.99-rc1 review patch. If anyone has any objections, please let me know.
------------------
From: Arnd Bergmann <arnd@xxxxxxxx>
commit 1dbc080c9ef6bcfba652ef0d6ae919b8c7c85a1d upstream.
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.
