Paolo 'Blaisorblade' Giarrusso c50d2c4d66 [PATCH] uml: fix mcast network driver error handling
printk clears the host errno (I verified this in debugging and it's reasonable
enough, given that it ends via a write call on some fd, especially since
printk() goes on /dev/tty0 which is often the host stdout).  So save errno
earlier.  There's no reason to change the printk calls to use -err rather than
errno - the assignment can't clear errno.

And in the first failure path, we used to return 0 too (and this time more
clearly), which is totally wrong.  0 is a success fd, which is then registered
and gives a "registering fd twice" warning.

Finally, fix up some whitespace.
