[PATCH 0/2] wifi: ath: Remove ath*_base::bd_api

[Jeff Johnson]

Both ath11k and ath12k inherited the bd_api member in their struct
ath*_base.  In ath10k this member is accessed from both
ath10k_core_fetch_board_file() and ath10k_debug_print_board_info(), so
it is justified. However, in ath11k and ath12k, this member is only
used within a single function, so it is not justified in those
drivers.

[PATCH 1/2] wifi: ath11k: Remove ath11k_base::bd_api

[Jeff Johnson]

Currently struct ath11k_base defines the member bd_api. However, this
member is only accessed within ath11k_core_fetch_bdf(). Since the
scope is local just to that one function, remove it from ath11k_base
and instead just use a local stack variable.

No functional changes, compile tested only.
