From: Andy Shevchenko <andriy.shevchenko@xxxxxxxxxxxxxxx> [ Upstream commit cb1d17535061ca295903f97f5cb0af9db719c02c ] min() has strict type checking and preferred over min_t() for unsigned types to avoid overflow. Here it's unclear why min_t() was chosen since both variables are of the same type. In any case update to use min().
