[PATCH 4.9 09/61] net: sun: fix missing release regions in cas_init_one().

From: Greg Kroah-Hartman
Date: Mon Jun 01 2020 - 13:59:33 EST


From: Qiushi Wu <wu000273@xxxxxxx>

commit 5a730153984dd13f82ffae93d7170d76eba204e9 upstream.

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.")
