From a5b90ef7a1fed3fc0f7a4bf0ad0159eaddb2acfb Mon Sep 17 00:00:00 2001 From: Daeseok Youn Date: Wed, 4 May 2016 14:13:48 +0900 Subject: staging: dgnc: clean up the dgnc_get_modem_info() the "ch" in dgnc_get_modem_info() was already checked before calling this function and also if "ch" is not NULL, dgnc_get_mstat() returns valid value so it doesn't need to check an error.
