Subject: [PATCH 21/22] cpuplugd: fix reading the size of /proc/sys/vm/cmm_pages
Description: cpuplugd: fix fscanf file handling in get_cmmpages_size
Symptom: cpuplugd was not able to correctly read the size of the
/proc/sys/vm/cmm_pages file. This prevented cpuplugd from using
the cmm feature correctly.
Problem: The code checked for the wrong return code (!= 0 instead of ==0)
Solution: Check for the right return code in the get_cmmpages_size error
handling function.
