[PATCH 5.1 120/138] staging: wilc1000: fix error path cleanup in wilc_wlan_initialize()

From: Greg Kroah-Hartman
Date: Fri Jul 12 2019 - 08:37:35 EST


From: Ajay Singh <ajay.kathat@xxxxxxxxxxxxx>

commit 6419f818ababebc1116fb2d0e220bd4fe835d0e3 upstream.

For the error path in wilc_wlan_initialize(), the resources are not
cleanup in the correct order. Reverted the previous changes and use the
correct order to free during error condition.

Fixes: b46d68825c2d ("staging: wilc1000: remove COMPLEMENT_BOOT")
