Issue of the Implementation # L0193

Brief

pxa168: double deallocation of managed resources

Detailed Description

Commit 43d3ddf87a57 ("net: pxa168_eth: add device tree support") starts to use managed resources by adding devm_clk_get() and devm_ioremap_resource(), but it leaves explicit iounmap() and clock_put() in pxa168_eth_remove() and in failure handling code of pxa168_eth_probe(). As a result double free can happen.
