Subject: [PATCH] net: bgmac-platform: handle mac-address deferral
|
|
|
|
This patch is a replication of Christian Lamparter's "net: bgmac-bcma:
|
|
handle deferred probe error due to mac-address" patch for the
|
|
bgmac-platform driver [1].
|
|
|
|
As is the case with the bgmac-bcma driver, this change is to cover the
|
|
scenario where the MAC address cannot yet be discovered due to reliance
|
|
on an nvmem provider which is yet to be instantiated, resulting in a
|
|
random address being assigned that has to be manually overridden.
