Subject: [PATCH v5 1/1] usb: ulpi: ulpi_init should be executed in subsys_initcall
Date: Thu, 4 Jun 2015 20:44:14 +0800 [thread overview]
Message-ID: <1433421854-24569-1-git-send-email-baolu.lu@linux.intel.com> (raw)
Phy drivers and the ulpi interface providers depend on the
registration of the ulpi bus. Ulpi registers the bus in
module_init(). This could cause unnecessary bus users'
probe delays. i.e. unnecessary -EPROBE_DEFER happening on
ulpi_drivers in case they're registered before ulpi bus
itself.
