The rule for the SoundWire tables is that the platforms with more
devices need to be added first. We broke that rule with the Dell SKU
0B34, and caused the second amplifier for SKU 0AF3 to be ignored.
The fix is simple, we need to move the single-amplifier entry after
the two-amplifier one.

Fix this by not generating all battery/charger properties when the

s390/bpf: Fix arch_prepare_bpf_trampoline
While working on trampoline, I found s390's arch_prepare_bpf_trampoline

catch this issue. Turns out test_progs:bpf_tcp_ca doesn't really test

indeed called by the trampoline. Without 1/2, this check would fail on

arch_prepare_bpf_trampoline() for s390 currently returns 0 on success. This
is not a problem for regular trampoline. However, struct_ops relies on the
return value to advance "image" pointer:
bpf_struct_ops_map_update_elem() {
...
for_each_member(i, t, member) {
...
err = bpf_struct_ops_prepare_trampoline();
...
image += err;
}
}
When arch_prepare_bpf_trampoline returns 0 on success, all members of the
struct_ops will point to the same trampoline (the last one).
Fix this by returning the program size in arch_prepare_bpf_trampoline (on
success). This is the same behavior as other architectures.
