linux-toradex.git/drivers/ptp/ptp_pch.c, branch v7.0-rc2 Linux kernel for Apalis and Colibri modules kernel.h: drop hex.h and update all hex.h users 2026-01-21T03:44:19+00:00 Randy Dunlap rdunlap@infradead.org 2025-12-15T00:51:56+00:00 24c776355f4097316a763005434ffff716aa21a8 Remove <linux/hex.h> from <linux/kernel.h> and update all users/callers of hex.h interfaces to directly #include <linux/hex.h> as part of the process of putting kernel.h on a diet. Removing hex.h from kernel.h means that 36K C source files don't have to pay the price of parsing hex.h for the roughly 120 C source files that need it. This change has been build-tested with allmodconfig on most ARCHes. Also, all users/callers of <linux/hex.h> in the entire source tree have been updated if needed (if not already #included).
