From b884e34994ca41f7b7819f3c41b78ff494787b27 Mon Sep 17 00:00:00 2001 From: Carlos Song Date: Wed, 10 Dec 2025 18:50:01 +0800 Subject: [PATCH] spi: spi-fsl-lpspi: convert min_t() to simple min() Current min() has supported comparison by normal integer promotion rules, so explicit type casts or min_t() are not needed.
