From ce09affc59bca2a1ac1f77b75915fd914fab1f70 Mon Sep 17 00:00:00 2001 From: "Kim, Milo" Date: Wed, 4 Jan 2012 09:03:18 +0400 Subject: [PATCH] lp8727_charger: Coding style changes 1. Useless braces were omitted 2. Useless void casts were omitted 3. module exit name changed lp8727_chg_exit -> lp8727_exit 4. Pointer coding style changes no space between pointer('*') and pointer name ex) u8 * data -> u8 *data 5.
