From: Ramesh Rangavittal <ramesh.rangavittal@xxxxxxxxxxxx>
When STA roams from one AP to another, after roam is complete, host
driver tries to get TIM information from firmware. This is no longer
supported in the firmware & hence, this call will always fail.
This failure results in the below message being displayed on the
console all the time when roam is done.
ieee80211 phy0: brcmf_update_bss_info: wl dtim_assoc failed (-52)
Changes ensure that the host driver will no longer try to get TIM
information from firmware.
