From a023da331c1d2a26669161031fe6e2c8e0a2009e Mon Sep 17 00:00:00 2001 From: Pavel Machek Date: Mon, 30 Sep 2013 14:56:02 +0200 Subject: [PATCH] usb: gadget: s3c-hsotg: fix CodingStyle issues checkpatch.pl has some valid complaints about style in s3c-hsotg.c: - macro with 'if' should be really enclosed in 'do {} while (0)' - seq_puts() is going to be slightly faster than seq_printf() - pr_err() is shorter than printk(KERN_ERR ...)
