From: Greg Kroah-Hartman Date: Thu, 3 May 2012 23:39:27 +0000 (-0700) Subject: USB: serial: pl2303: convert dbg() calls to dev_dbg() X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=d8789b2b90aeb53ce59ac232d2ff0d8357d53893;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git USB: serial: pl2303: convert dbg() calls to dev_dbg() This converts the usage of dbg() to dev_dbg() where needed, and removed a bunch of these calls where they were just "tracing" calls, which are no longer needed.
