Subject: [PATCH 3/3] staging: dgnc: clean up the dgnc_get_modem_info()
Date: Wed, 04 May 2016 05:13:48 +0000 [thread overview]
Message-ID: <20160504051348.GA21479@certreview.com> (raw)
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.
