From 2cf8e2dfdf88363476f23bc600745250b94dbbed Mon Sep 17 00:00:00 2001 From: Charles Keepax Date: Thu, 12 Jan 2017 11:17:39 +0000 Subject: regmap: Fixup the kernel-doc comments on functions/structures Most of the kernel-doc comments in regmap don't actually generate correctly. This patch fixes up a few common issues, corrects some typos and adds some missing argument descriptions. The most common issues being using a : after the function name which causes the short description to not render correctly and not separating the long and short descriptions of the function. There are quite a few instances of arguments not being described or given the wrong name as well. This patch doesn't fixup functions/structures that are currently missing descriptions.
