From: Dan Carpenter Date: Fri, 19 Oct 2018 20:11:11 +0000 (+0300) Subject: qlcnic: fix a return in qlcnic_dcb_get_capability() X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=5817a818d24ccaaf56d52594c74543c268beabfb;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git qlcnic: fix a return in qlcnic_dcb_get_capability() [ Upstream commit c94f026fb742b2d3199422751dbc4f6fc0e753d8 ] These functions are supposed to return one on failure and zero on success. Returning a zero here could cause uninitialized variable bugs in several of the callers. For example: drivers/scsi/cxgbi/cxgb4i/cxgb4i.c:1660 get_iscsi_dcb_priority() error: uninitialized symbol 'caps'. Fixes: 48365e485275 ("qlcnic: dcb: Add support for CEE Netlink interface.")
