[PATCH 2/7] pcie-gadget-spear: Add "platform:" prefix for platform modalias

[Greg Kroah-Hartman]

From: Axel Lin <axel.lin@gmail.com>

Since 43cc71eed1250755986da4c0f9898f9a635cb3bf (platform: prefix MODALIAS
with "platform:"), the platform modalias is prefixed with "platform:".

[PATCH 6/7] pch_phub: Fix MAC address writing issue for LAPIS ML7831

[Greg Kroah-Hartman]

From: Tomoya MORINAGA <tomoya.rohm@gmail.com>

ISSUE:
Using ML7831, MAC address writing doesn't work well.

CAUSE:
ML7831 and EG20T have the same register map for MAC address access.
However, this driver processes the writing the same as ML7223.
This is not true.
This driver must process the writing the same as EG20T.
This patch fixes the issue.
