Subject: [PATCH 2/3] btmrvl: set irq_bt to -1 when failed to parse it
Date: Fri, 20 Jan 2017 19:14:19 +0800	[thread overview]
Message-ID: <1484910860-7690-2-git-send-email-jeffy.chen@rock-chips.com> (raw)
In-Reply-To: <1484910860-7690-1-git-send-email-jeffy.chen@rock-chips.com>

The irq_of_parse_and_map will return 0 as a invalid irq.

Set irq_bt to -1 in this case, so that the btmrvl resume/suspend code
would not get confused.
