Subject: [PATCH 1/8] lpfc: Revert LOG_TRACE_EVENT back to LOG_INIT prior to driver_resource_setup
Date: Wed, 20 Oct 2021 14:14:10 -0700	[thread overview]
Message-ID: <20211020211417.88754-2-jsmart2021@gmail.com> (raw)
In-Reply-To: <20211020211417.88754-1-jsmart2021@gmail.com>

In cases when lpfc_enable_pci_dev fails, lpfc_printf_log with
LOG_TRACE_EVENT set will call lpfc_dmp_dbg which uses the
phba->port_list_lock.

However, phba->port_list_lock does not get initialized until
lpfc_setup_driver_resource_phase1.  Thus, any initialization routine with
LOG_TRACE_EVENT log message prior to lpfc_setup_driver_resource_phase1
will crash.

Revert LOG_TRACE_EVENT back to LOG_INIT for all log messages in routines
prior to lpfc_setup_driver_resource_phase1.
