Subject: [PATCH] mt76: mt7615: move drv_own/fw_own in mt7615_mcu_ops
Git-commit: 186b659c0859704ef3b2fb634a659724f020889a
Patch-mainline: v5.10-rc1
References: git-fixes
Introduce set_drv_ctrl and set_fw_ctrl function pointers in
mt7615_mcu_ops data structure. This is a preliminary patch to enable
runtime-pm for non-pci chipsets
