Subject: [PATCH 1/2] signalfd: fix error return code
If anon_inode_getfile() fails, return appropriate error code. This looks
like a single typo: the similar code changes in timerfd and userfaultfd
are okay.
Found by Linux Verification Center (linuxtesting.org).
Fixes: fbe38120eb1d ("signalfd: convert to ->read_iter()")
