[PATCH v2] x86/platform/goldfish: add a check for platform_device_register_simple

From: Chuhong Yuan
Date: Mon Dec 09 2019 - 22:16:12 EST


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

Fixes: ddd70cf93d78 ("goldfish: platform device for x86")

Changes in v2:
- Use PLATFORM_DEVID_NONE instead of -1.
- Use PTR_ERR_OR_ZERO() to simplify the code.
