Subject: [PATCH] net: bgmac: fix reversed checks for clock control flag
|
|
|
|
|
|
|
|
|
|
This fixes regression introduced by patch adding feature flags. It was
|
|
|
|
|
already reported and patch followed (it got accepted) but it appears it
|
|
|
|
|
was incorrect. Instead of fixing reversed condition it broke a good one.
|
|
|
|
|
|
|
|
|
|
This patch was verified to actually fix SoC hanges caused by bgmac on
|
|
|
|
|
BCM47186B0.
|
|

|
|
|
|
|
Fixes: 4af1474e6198 ("net: bgmac: Fix errant feature flag check")
