Subject: [PATCH] PCI/VGA: Select SCREEN_INFO
Date: Mon, 13 Oct 2025 08:59:28 -0500 [thread overview]
Message-ID: <20251013135929.913441-1-superm1@kernel.org> (raw)
commit 337bf13aa9dda ("PCI/VGA: Replace vga_is_firmware_default() with
a screen info check") introduced an implicit dependency upon SCREEN_INFO
by removing the open coded implementation.
If a user didn't have CONFIG_SCREEN_INFO set vga_is_firmware_default()
would now return false. Add a select for SCREEN_INFO to ensure that the
VGA arbiter works as intended.
