When the driver is removed s3c_hsotg_phy_disable is called three times instead of once. This results in decreasing of the phy reference counter below zero and thus consecutive inserts of the module fails. This patch removes calls to s3c_hsotg_phy_disable from s3c_hsotg_remove and s3c_hsotg_udc_stop. s3c_hsotg_udc_stop is called from udc-core.c only after usb_gadget_disconnect, which in turn calls s3c_hsotg_pullup, which already calls s3c_hsotg_phy_disable. s3c_hsotg_remove must be called only after udc_stop, so there is no point in disabling phy once again there.
