Subject: NFC: st21nfcb: Remove inappropriate kfree on a devm_kzalloc pointer
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=38bd83f04c5e9695011dc5c294e0c4e6a9f9052d;p=deliverable%2Flinux.git

NFC: st21nfcb: Remove inappropriate kfree on a devm_kzalloc pointer

Since ndev->driver_data is allocated by devm_kzalloc(), we do not
need the inappropriate kfree to free it in driver's remove function.
Freeing will trigger when driver unloads.
