Subject: [PATCH] fpga: dfl: add missing platform_device_put in build_info_create_dev
Date: Wed, 25 Nov 2020 14:50:30 +0800	[thread overview]
Message-ID: <20201125065030.154074-1-miaoqinglang@huawei.com> (raw)

platform_device_put is missing when it fails to set fdev->id. Set
a temp value to do sanity check.

Fixes: 543be3d8c999 ("fpga: add device feature list support")
Reported-by: Hulk Robot <hulkci@huawei.com>
