Subject: [PATCH 1/3] net: airoha: Do not store hfwd references in airoha_qdma
|
|
struct
|
|
|
|
Since hfwd descriptor and buffer queues are allocated via
|
|
dmam_alloc_coherent() we do not need to store their references
|
|
in airoha_qdma struct. This patch does not introduce any logical changes,
|
|
just code clean-up.
