[PATCH 0/3] HID: bpf: fix 7.3-rc0 bpf breakage

[Benjamin Tissoires]

With the introduction of commit ee9ad135b208 ("bpf: Reject a store
through a fault prone pointer"), a HID-BPF program which would try to
change the name, phys or uniq of a HID device would be rejected by the
verifier. Also, this commits and its siblings manage to detect the
buffer overflow that is currently dynamically detected in the test
suite. The verifier now rejects the bpf program we try to load, marking
the test as fail. This is correct behavior, and better admittedly so fix
this so the CI stays green.
