Subject[PATCH] hotplug/drc-info: ininitialize fndit to zero
Date
From: Colin Ian King <colin.king@canonical.com>

Currently variable fndit is not initialized and contains a
garbage value, later it is set to 1 if a drc entry is found.
Ensure fndit is not containing garbage by initializing it to
zero. Also remove an extraneous space at the end of an
sprintf call.

Detected by static analysis with cppcheck.

Fixes: 2fcf3ae508c2 ("hotplug/drc-info: Add code to search ibm,drc-info property")
