Subject: io_uring: initialize 'timeout' properly in io_sq_thread()
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=a0d9205f7d36bf72279f34a93850fd14789fdc7e;p=linux.git

io_uring: initialize 'timeout' properly in io_sq_thread()

Some static checker reports below warning:
    fs/io_uring.c:6939 io_sq_thread()
    error: uninitialized symbol 'timeout'.

This is a false positive, but let's just initialize 'timeout' to make
sure we don't trip over this.
