Since you're going to be resending anyway, please delete the space char
from the start of the line.
It's weird that brcmf_fil_cmd_data_get() uses the uninitialized data.
It looks like it just goes to great lengths to preserve the original
data in io_type... So it likely is harmless enough but still a strange
and complicated way write a no-op.
