[patch v1 1/1] platform/x86: mlx-platform: mlxcpld-hotplug driver style fixes

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 

The patch contains several styling fixes:
  - Make names of hotplug devices shorter;
  - Change register offset assignment to defines;
  - Add defines for the all event masks;
  - Use PLATFORM_DEVID_NONE instead of -1;
