ccollins476ad opened a new pull request #1025: imgmgr: Prevent `maybe-uninitialized` warning.
URL: https://github.com/apache/mynewt-core/pull/1025
 
 
   gcc 5.4.1 reports the following warning when `BOOTUTIL_IMAGE_FORMAT_V2` is enabled:
   
   ```
   Error: repos/apache-mynewt-core/mgmt/imgmgr/src/imgmgr.c: In function 'imgr_read_info':
   repos/apache-mynewt-core/mgmt/imgmgr/src/imgmgr.c:202:16: error: 'data_end' may be used uninitialized in this function [-Werror=maybe-uninitialized]
                if (data_off + IMGMGR_HASH_LEN > data_end) {
                   ^
   ```
   
   This is a spurious warning; `data_end` is always initialized at this point.  The fix is to initialize `data_end` to 0 at the start of the function.
