If anyone has any objections, please let me know. ------------------ From: Min zhang [ Upstream commit a8036f4591542de4b38ec81d3e2ba47bc0b2652b ] Using devm_kmalloc() does not zero-initialize the allocated structure. Uninitialized members in struct hisi_reset_controller may contain garbage data, which can cause reset_controller_register() to fail unexpectedly. Replace devm_kmalloc() with devm_kzalloc() to ensure all structure fields are properly zero-initialized.
