Subject: [PATCH v3 08/13] usb: gadget: bcm63xx_udc: create debugfs directory under usb root
Date: Thu, 14 Nov 2019 18:41:20 +0800	[thread overview]
Message-ID: <1573728085-29016-8-git-send-email-chunfeng.yun@mediatek.com> (raw)
In-Reply-To: <1573728085-29016-1-git-send-email-chunfeng.yun@mediatek.com>

Now the USB gadget subsystem can use the USB debugfs root directory,
so move it's directory from the root of the debugfs filesystem into
the root of usb

Signed-off-by: Chunfeng Yun <chunfeng.yun@mediatek.com>

v3:
  1. fix up build error of undefined usb_debug_root

v2:
  1. abandon new API usb_debugfs_create_dir(), and use usb_debug_root
