Title
wifi: mt76: mt7915: Fix null-ptr-deref in mt7915_mmio_wed_init()
Summary
In the Linux kernel, the following vulnerability has been resolved:
wifi: mt76: mt7915: Fix null-ptr-deref in mt7915_mmio_wed_init()
devm_ioremap() returns NULL on error. Currently, mt7915_mmio_wed_init()
does not check for this case, which results in a NULL pointer
dereference.
Prevent null pointer dereference in mt7915_mmio_wed_init().
