Subject: [PATCH] drm/bochs: downgrade pci_request_region failure from error to warning
Mime-version: 1.0

Git-commit: 8c34cd1a7f089dc03933289c5d4a4d1489549828
Patch-mainline: v5.6-rc7
References: bsc#1051510
Shutdown of firmware framebuffer has a bunch of problems. Because
of this the framebuffer region might still be reserved even after
drm_fb_helper_remove_conflicting_pci_framebuffers() returned.
Don't consider pci_request_region() failure for the framebuffer
region as fatal error to workaround this issue.
