From: Sergei Shtylyov <sergei.shtylyov@...entembedded.com>
To: netdev@...r.kernel.org
Subject: [PATCH 1/6] phy: coding style fixes
The recent patch from Florian Fainelli fixed all 'checkpatch.pl' errors but left
the numerous warnings like:
- including <asm/io.h> instead of <linux/io.h>;
- including <asm/uaccess.h> instead of <linux/uaccess.h>;
- block comments using empty /* line;
- block comments not starting with * on the middle lines;
- block comments not having trailing */ on a separate line;
- EXPORT_SYMBOL() not immediately following its function;
- unnecessary {} for signle statement block;
- spaces before tabs.
While fixing these, also fix the following style issues (some of which were
found running 'checkpatch.pl --strict'):
- alignment not matching open paren;
- missing {} on one of the *if* arms where another has them;
- use of sizeof(struct structure) instead of sizeof(*variable);
- multiple assignments on one line;
- empty line before };
- file names in the heading comments;
- missing spaces around operators;
- no {} around multi-line *if* operator's arm;
- unneeded () around subexpressions;
- incomplete kernel-doc comment style;
- comment line exceeding 80 characters;
- missing empty line after declarations.
