Don't you want to mask with 0x01 to explicitly check bit 0? I imagine
the other bits may be used for something else in the future.

dmi_string() can't return NULL so the first test isn't needed.
For the rest, I think strncmp(str, " ", 2) would be more readable. If
you still prefer to open-code it, note that you could use str[0] to
test the first char and str[1] to test the second char, which would
make the intentions more obvious. Both options would let you reuse str
in pr_attr().
(Personally I would only test the first char as I can't imagine a valid
filename starting with a space, but you'll know better.)
You can tell me what you prefer and I'll edit before committing, if you
don't want to resend.
