[PATCH AUTOSEL 4.4 6/7] net: sun: fix missing release regions in cas_init_one().

From: Sasha Levin
Date: Thu May 28 2020 - 07:59:31 EST


From: Qiushi Wu <wu000273@xxxxxxx>

[ 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 âpci_write_config_byteâ
failed. Thus replace the jump target âerr_write_cachelineâ by
"err_out_free_res".

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