On 64-bit systems,\na value \u003e 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 \u003c 1 to reject the 0-delay case, which would cause the poll work to\nspin without delay and consume 100%
