Subject: [PATCH AUTOSEL 4.9 7/9] net: sun: fix missing release regions in cas_init_one().

From: Qiushi Wu <wu000273@....edu>

[ Upstream commit 5a730153984dd13f82ffae93d7170d76eba204e9 ]

In cas_init_one(), "pdev" is requested by "pci_request_regions", but it
was not released after a call of the function “pci_write_config_byte”
failed. Thus replace the jump target “err_write_cacheline” by
"err_out_free_res".

Fixes: 1f26dac32057 ("[NET]: Add Sun Cassini driver.")
