Subject: [PATCH AUTOSEL 4.14 07/40] usb: dwc3: gadget: synchronize_irq dwc irq in suspend
Date: Thu, 14 Feb 2019 21:12:40 -0500	[thread overview]
Message-ID: <20190215021313.178476-7-sashal@kernel.org> (raw)
In-Reply-To: <20190215021313.178476-1-sashal@kernel.org>

From: Bo He <bo.he@intel.com>

[ Upstream commit 01c10880d24291a96a4ab0da773e3c5ce4d12da8 ]

We see dwc3 endpoint stopped by unwanted irq during
suspend resume test, which is caused dwc3 ep can't be started
with error "No Resource".

Here, add synchronize_irq before suspend to sync the
pending IRQ handlers complete.
