Technical description

In the Linux kernel, the following vulnerability has been resolved:

wifi: mt76: mt7921: fix kernel panic due to null pointer dereference

Address a kernel panic caused by a null pointer dereference in the

`mt792x_rx_get_wcid` function. The issue arises because the `deflink` structure

is not properly initialized with the `sta` context. This patch ensures that the

`deflink` structure is correctly linked to the `sta` context, preventing the

null pointer dereference.
