On 64-bit systems,\na value > UINT_MAX is silently truncated when stored.\n\nFix the mismatch by using kstrtouint() instead. This rejects values larger\nthan UINT_MAX at parse time, making truncation impossible. Also add a check\nfor value < 1 to reject the 0-delay case, which would cause the poll work to\nspin without delay and consume 100% CPU."
