Subject: [PATCH v2] x86/platform/goldfish: add a check for platform_device_register_simple
Date: Tue, 10 Dec 2019 11:15:59 +0800	[thread overview]
Message-ID: <20191210031559.18715-1-hslester96@gmail.com> (raw)

goldfish_init() misses a check for platform_device_register_simple().
Add a check to fix it.

Fixes: ddd70cf93d78 ("goldfish: platform device for x86")
Signed-off-by: Chuhong Yuan <hslester96@gmail.com>
---
Changes in v2:
  - Use PLATFORM_DEVID_NONE instead of -1.
  - Use PTR_ERR_OR_ZERO() to simplify the code.
