[PATCH 6.0 719/862] hwmon: (sht4x) do not overflow clamping operation on 32-bit platforms

[Greg Kroah-Hartman]

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.
