From: "Jason A. Donenfeld" <Jason@xxxxxxxxx> [ Upstream commit f9c0cf8f26de367c58e48b02b1cdb9c377626e6f ] On 32-bit platforms, long is 32 bits, so (long)UINT_MAX is less than (long)SHT4X_MIN_POLL_INTERVAL, which means the clamping operation is bogus. Fix this by clamping at INT_MAX, so that the upperbound is the same on all platforms. Signed-off-by: Jason A.
