If anyone has any objections, please let me know. ------------------ From: Runyu Xiao [ Upstream commit 1329abe1bae416ab2cff89c3312d33f745d341c7 ] Registering the HTE chip publishes its request callbacks to consumers. Initialize every slice lock before registration so a concurrent HTE request cannot use an uninitialized lock.
