Subject[PATCH 2/2] spi: Prevent a type mismatch warning using min_t()
Date
From: Thierry Reding <treding@nvidia.com>

The min_t() variant of the min() macro uses an explicit cast to the type
given in the first argument and can be used to avoid a compiler warning
if both types differ (f.e. in signedness).
