- Subject: [PATCH] fix return of uninitialized variable
- MIME-Version: 1.0
- Content-Type: text/plain; charset=UTF-8
- Content-Transfer-Encoding: 8bit
- atasmart.c: In function ‘init_smart’:
- atasmart.c:2556: warning: ‘ret’ may be used uninitialized in this function
- We apparently don't initialize the ret variable in init_smart() -
- unfortunately
- o this warning is never reported with using -O0 (thanks gcc -
- see http://gcc.gnu.org/wiki/Better_Uninitialized_Warnings though)
- o we never run into this bug with just skdump(1)
- The bug does show up in the udisks (aka DeviceKit-disks) use of
- libatasmart and this patch fixes it.
