Subject: [PATCH v2 7/9] PCI: hotplug: Prefer CONFIG_DYNAMIC_DEBUG/DEBUG for dmesg logs
Date: Thu, 2 May 2019 22:59:44 -0500 [thread overview]
Message-ID: <20190503035946.23608-8-fred@fredlawl.com> (raw)
In-Reply-To: <20190503035946.23608-1-fred@fredlawl.com>
dbg() and ctrl_dbg() requires pciehp_debug module parameter to be set
for debug log purposes. There are niche situations in pciehp_hpc.c where
pciehp_debug is used: dbg_ctrl(), and pci_bus_check_dev().
Enabling CONFIG_DYNAMIC_DEBUG/DEBUG is well known for logging debug
information. Therefore, prefer pr/pci_dbg() for debug information, and
reserve pciehp_debug for niche situations.
