Subject: oprofile, arm: initialize perf_event pointers with NULL
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=4cbe75be5c6ae86bdc7daec864eeb2dfd66f48bb;p=linux-beck.git

oprofile, arm: initialize perf_event pointers with NULL

The pointers must be NULL'ed to avoid double-freeing the pointers in
rare cases during reinitialization.
