From 860cbe92ff2168eff1b0a28ff61c3573900ac9d0 Mon Sep 17 00:00:00 2001 From: Marek Vasut Date: Wed, 26 Jun 2019 01:43:41 +0200 Subject: [PATCH] net: dsa: microchip: Inline ksz_spi.h The functions in the header file are static, and the header file is included from single C file, just inline the code into the C file. The bonus is that it's easier to spot further content to clean up.
