Subject: [PATCH 3/8] ::Kirin:: Remove lock to prevent self-lock
|
|
|
|
With Huawei Camera HAL, we get the following call order:
|
|
cameraserver CameraService::enumerateProviders (*)
|
|
=> HAL ICameraProvider::getVendorTags
|
|
=> HAL ICameraProviderCallback::cameraDeviceStatusChange
|
|
=> cameraserver CameraService::addState
|
|
=> cameraserver CameraService::updateCameraNumAndIds (*)
|
|
|
|
The two functions marked with (*) take mServiceLock
|
|
Hence the safe-lock
