net: macb: replace min() with umin() calls
Whenever min(a, b) is used with a and b unsigned variables or literals, `make W=2` complains. Change four min() calls into umin(). stderr extract (GCC 11.2.0, MIPS Codescape): ./include/linux/minmax.h:68:57: warning: comparison is always true due to limited range of data type [-Wtype-limits] 68 | #define __is_nonneg(ux) statically_true((long long)(ux) >= 0) | ^~ drivers/net/ethernet/cadence/macb_main.c:2299:26: note: in expansion of macro ‘min’ 2299 | hdrlen = min(skb_headlen(skb), bp->max_tx_length); | ^~~ Signed-off-by: Théo Lebrun <theo.lebrun@bootlin.com> Link: https://patch.msgid.link/20251014-macb-cleanup-v1-11-31cd266e22cd@bootlin.com Signed-off-by: Jakub Kicinski <kuba@kernel.org>
