hwmon: (nct6775-core) Fix overflows seen when writing limit attributes
[ Upstream commit 57ee12b6c514146c19b6a159013b48727a012960 ]
DIV_ROUND_CLOSEST() after kstrtoul() results in an overflow if a large
number such as 18446744073709551615 is provided by the user.
Fix it by reordering clamp_val() and DIV_ROUND_CLOSEST() operations.
