This patch removes a variable from fs/cramfs/inode.c that is just used to
store
a return value which is immediately read afterwards.
Tested on an i386 box.

Maybe picky but please leave it as "if (".
Beyond that, I just don't like this change. I thought the preferred way
for these types of statements was the previous version. That is:
error = filldir(...);
if (error)
error stuff
Rather than a conditional with potential side-effects?
Which side-effects are you thinking of? We quite often have:
if (!if_this_fails_it_all_fails())
return -FAILED;
but we also have:
if ((p = malloc(...)) == NULL)
...
and that is a different story (IMHO).
But I don't mind either way...
(the compiler will get rid of it anyway, right?)
