From 1e684172358453df1cb783d7c101a09ff08ceee1 Mon Sep 17 00:00:00 2001 From: Luis Chamberlain Date: Sun, 19 Mar 2023 14:27:37 -0700 Subject: [PATCH] module: add a for_each_modinfo_entry() Add a for_each_modinfo_entry() to make it easier to read and use. This produces no functional changes but makes this code easiert to read as we are used to with loops in the kernel and trims more lines of code.
