From: Toshiaki Yamane <yamanetoshi@...il.com>
To: Greg Kroah-Hartman <greg@...ah.com>
Cc: linux-kernel@...r.kernel.org,
Toshiaki Yamane <yamanetoshi@...il.com>
Subject: [PATCH 1/2] staging/rts_pstor: Use pr_ printks in rtsx.c
fixed some checkpatch warnings.
-WARNING: Prefer pr_info(... to printk(KERN_INFO, ...
-WARNING: Prefer pr_err(... to printk(KERN_ERR, ...
-WARNING: quoted string split across lines
And added pr_fmt.
