This is not an issue with the max2175 driver, but with the
regmap_read_poll_timeout() macro:
#define regmap_read_poll_timeout(map, addr, val, cond, sleep_us,
timeout_us) \
({ \
...
if (timeout_us && ktime_compare(ktime_get(), timeout) > 0) { \
For increased safety, and to avoid this warning, "timeout_us" should be
inside parentheses.
