If anyone has any objections, please let me know. ------------------ From: Christian Marangi [ Upstream commit 04305367fab7ec9c98eeba315ad09c8b20abce93 ] To clean Mediatek SoC PCIe struct, convert all the bool to a bitmap and use a single quirks to reference all the values. This permits cleaner addition of new quirk without having to define a new bool in the struct.
