Subject: [PATCH] wifi: ath11k: Add missing check for ioremap
|
||
|
|
|
||
|
|
Add check for ioremap() and return the error if it fails in order to
|
||
|
|
guarantee the success of ioremap(), same as in
|
||
|
|
ath11k_qmi_load_file_target_mem().
|
||
|
|
|
||
|
|
Fixes: 6ac04bdc5edb ("ath11k: Use reserved host DDR addresses from DT for PCI devices")
