[PATCH char-misc-next 2/4] misc: mic: return error properly

[Sudip Mukherjee <sudipm.mukherjee@gmail.com>]

If request_firmware() succeeds then rc becomes 0. After that if the test
for strcmp() fails then we were jumping to label done: and returning rc.
But rc being 0 we returned success whereas we have failed here and we
were supposed to return an error.

I am not sure if this was intentional. Another case might be that if the
string bootmode is "flash" then mic_x100_load_command_line() was
intentionally skipped and success was returned.
