2025-05-22wifi: mt76: mt7996: Fix null-ptr-deref in mt7996_mmio_wed_init()Henry Martin
devm_ioremap() returns NULL on error. Currently, mt7996_mmio_wed_init() does not check for this case, which results in a NULL pointer dereference. Prevent null pointer dereference in mt7996_mmio_wed_init() Fixes: 83eafc9251d6 ("wifi: mt76: mt7996: add wed tx support") Signed-off-by: Henry Martin <bsdhenrymartin@gmail.com> Link: https://patch.msgid.link/20250407032349.83360-1-bsdhenrymartin@gmail.com Signed-off-by: Felix Fietkau <nbd@nbd.name>

2025-05-21wifi: mt76: mt7996: add macros for pci device idsShayne Chen
The chipset name (i.e., brand name) used by the driver may cause confusion with the PCI device ID when adding support for new chipsets. | Chipset name | PCI device id | |--------------|----------------| | 7996 | 0x7990, 0x7991 | | 7992 | 0x7992, 0x799a | | 7990 | 0x7993, 0x799b | To prevent confusion, replace the code that directly uses the device ID with macros.
