[PATCH 4.19 220/639] drm/nouveau: fix missing break in switch statement
From: Greg Kroah-Hartman
Date: Fri Jan 24 2020 - 06:12:04 EST
From: Colin Ian King <colin.king@xxxxxxxxxxxxx>
[ Upstream commit 785cf1eeafa23ec63f426d322401054d13abe2a3 ]
The NOUVEAU_GETPARAM_PCI_DEVICE case is missing a break statement and falls
through to the following NOUVEAU_GETPARAM_BUS_TYPE case and may end up
re-assigning the getparam->value to an undesired value. Fix this by adding
in the missing break.
Detected by CoverityScan, CID#1460507 ("Missing break in switch")
Fixes: 359088d5b8ec ("drm/nouveau: remove trivial cases of nvxx_device() usage")
