Subject: [PATCH] [PATCH] vmcore-dmesg/vmcore-dmesg.c: Fix shifting error
reported by cppcheck
Running 'cppcheck' static code analyzer (see cppcheck(1))
on 'vmcore-dmesg/vmcore-dmesg.c' shows the following
shifting error:
$ cppcheck --enable=all vmcore-dmesg/vmcore-dmesg.c
Checking vmcore-dmesg/vmcore-dmesg.c ...
[vmcore-dmesg/vmcore-dmesg.c:17]: (error) Shifting signed 32-bit value
by 31 bits is undefined behaviour
Fix the same via this patch.
