Summary:
When simultaneous playback and capture end, input/output error will occur.
This issue is moved from firmware issue thesofproject/sof#180

Reproduce step:

binder: fix CONFIG_ANDROID_BINDER_DEVICES
793c823 
Several users have tried to only rely on binderfs to provide binder devices
and set CONFIG_ANDROID_BINDER_DEVICES="" empty. This is a great use-case of
binderfs and one that was always intended to work. However, this is
currently not possible since setting CONFIG_ANDROID_BINDER_DEVICES="" emtpy
will simply panic the kernel:

So check for the empty string since strsep() will otherwise return the
emtpy string which will cause kobject_add_internal() to panic when trying
to add a kobject with an emtpy name.

selftests/bpf: Test bpf_mprog query API via libbpf and raw syscall
f9b0879 
Add a new test case which performs double query of the bpf_mprog through
libbpf API, but also via raw bpf(2) syscall. This is testing to gather
first the count and then in a subsequent probe the full information with
the program array without clearing passed structs in between.
