Subject: usb: ulpi: ulpi_init should be executed in subsys_initcall
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=4696b8874d7de39850931888bc9f2aa12d29fb46;p=linux-beck.git

usb: ulpi: ulpi_init should be executed in subsys_initcall

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.
