Subject: [PATCH AUTOSEL 6.4 08/25] iio: core: Use min() instead of min_t() to make code more robust
From: Andy Shevchenko <andriy.shevchenko@...ux.intel.com>
[ 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().
