[PATCH 4.4 35/48] qlcnic: fix missing release in qlcnic_83xx_interrupt_test.

From: Greg Kroah-Hartman
Date: Mon Jun 01 2020 - 13:57:19 EST


From: Qiushi Wu <wu000273@xxxxxxx>

commit 15c973858903009e995b2037683de29dfe968621 upstream.

In function qlcnic_83xx_interrupt_test(), function
qlcnic_83xx_diag_alloc_res() is not handled by function
qlcnic_83xx_diag_free_res() after a call of the function
qlcnic_alloc_mbx_args() failed. Fix this issue by adding
a jump target "fail_mbx_args", and jump to this new target
when qlcnic_alloc_mbx_args() failed.

Fixes: b6b4316c8b2f ("qlcnic: Handle qlcnic_alloc_mbx_args() failure")
