From: Michael Chan Date: Mon, 9 Jul 2018 06:24:49 +0000 (-0400) Subject: bnxt_en: Always set output parameters in bnxt_get_max_rings(). X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=cab718feb18f6e4900f8951e966804d988d39a2d;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git bnxt_en: Always set output parameters in bnxt_get_max_rings(). [ Upstream commit 78f058a4aa0f2280dc4d45d2c4a95728398ef857 ] The current code returns -ENOMEM and does not bother to set the output parameters to 0 when no rings are available. Some callers, such as bnxt_get_channels() will display garbage ring numbers when that happens. Fix it by always setting the output parameters.
