crypto: crypto4xx - fix a potential double free in ppc4xx_trng_probe
There is a possible double free issue in ppc4xx_trng_probe():
85: dev->trng_base = of_iomap(trng, 0);
86: of_node_put(trng); ---> released here
87: if (!dev->trng_base)
88: goto err_out;
...
110: ierr_out:
111: of_node_put(trng); ---> double released here
...
This issue was detected by using the Coccinelle software.
We fix it by removing the unnecessary of_node_put().
