Subject: [PATCH RESEND] mpt3sas:Fix missing error checks for calls to _transport_phy_reset in mpt3sas_transport.c
Date: Sat,  2 Jul 2016 15:21:59 -0400	[thread overview]
Message-ID: <1467487319-30989-1-git-send-email-xerofoify@gmail.com> (raw)

This adds the missing error checks and paths for functions that
call _transport_phy_reset and do not correctly check that the
call to this particular function has succeeded by returning zero
in the file, mpt3sas_transport.c.
