Subject: power: remove redundant close of frequency file
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=64f22b91c6694e71a5163e7f33a55655fd260f90;p=dpdk.git

power: remove redundant close of frequency file

Previous fix has addressed the incorrect handling of `base_frequency`
file, but has added a use-after-free error due to the fact that all
further code paths will lead to an `fclose()` call at the end, so the
additional `fclose()` call right after processing the file was
unnecessary.

Coverity issue: 369901
Fixes: 8a5febaac4f7 ("power: fix P-state base frequency handling")
