[PATCH 4/5] bluetooth: Remove device_remove_all()

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



The function did two things: set device_info_valid to -1 and called
device_free() for each device in the hashmap. Setting
device_info_valid to -1 was unnecessary. The main purpose of that was
to fire DEVICE_CONNECTION_CHANGED as a side effect, but that hook is
fired anyway in device_free(), as a side effect of removing all
transports. Calling device_free() can be delegated to pa_hashmap, when
freeing or emptying it.
