stable inclusion from linux-4.19.207 commit 4a3dd774453aae49c8987decb0ab86f8eb349cc4
--------------------------------
[ Upstream commit 6b430c7595e4eb95fae8fb54adc3c3ce002e75ae ]
A successful 'init_rs_non_canonical()' call should be balanced by a corresponding 'free_rs()' call in the error handling path of the probe, as already done in the remove function.
Update the error handling path accordingly.
