Daniel Lezcano 2b718bb18f powercap: dtpm_cpu: Fix error check against freq_qos_add_request() 
[ Upstream commit b50155cb0d ]

The caller of the function freq_qos_add_request() checks again a non
zero value but freq_qos_add_request() can return '1' if the request
already exists. Therefore, the setup function fails while the QoS
request actually did not failed.

Fix that by changing the check against a negative value like all the
other callers of the function.

Fixes: 0e8f68d7f0 ("Add CPU energy model based support")
