X-Git-Tag: firefly_0821_release~3680^2~2299^2~6
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=178d855e7810deecb7fa96afdf82ec45b0284233;p=firefly-linux-kernel-4.4.55.git

virtio: rng: split out common code in probe / remove for s3/s4 ops

The freeze/restore s3/s4 operations will use code that's common to the
probe and remove routines.  Put the common code in separate funcitons.
