Subject: [PATCH] net: airoha: Fix an error handling path in airoha_probe()
|
|
|
|
If an error occurs after a successful airoha_hw_init() call,
|
|
airoha_ppe_deinit() needs to be called as already done in the remove
|
|
function.
|
|
|
|
Fixes: 00a7678310fe ("net: airoha: Introduce flowtable offload support")
