Subject: [PATCH 5.2 36/61] staging: wilc1000: fix error path cleanup in wilc_wlan_initialize()

From: Ajay Singh <ajay.kathat@...rochip.com>

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")
