Subject: [PATCH] usb: gadget: s3c-hsotg: fix CodingStyle issues
From: Pavel Machek <pavel@...x.de>
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 ...)
