Subject: [PATCH] net: dsa: ocelot: alloc memory for dsa switch instance
|
||
|
|
|
||
|
|
The dsa switch instance hasn't alloc memory for switch ports in felix
|
||
|
|
initialization driver, which will cause NULL pointer issue. Using
|
||
|
|
dsa_switch_alloc to alloc memory for dsa switch instance.
