From 86e4cb35f2260374df4139c2352afe7fe247cb60 Mon Sep 17 00:00:00 2001 From: Kuninori Morimoto Date: Mon, 6 Aug 2012 18:06:53 -0700 Subject: [PATCH] usb: host: ehci-platform: BUG_ON() to WARN_ON() on probe usb_ehci_pdata is certainly required in ehci-platform driver. This patch avoids using BUG_ON() from driver, and return from probe with WARN_ON() if pdata was NULL.
