[PATCH] serial: 8250_pci: fix -Winitializer-overrides for Brainboxes UC-260/271/701/756 entries
From: Rosen Penev
Date: Thu May 28 2026 - 16:15:23 EST
PCI_VDEVICE() expands to set .class=0 and .class_mask=0, but the Brainboxes
UC-260/271/701/756 entries immediately override those fields. This causes
a build error with clang -Werror,-Winitializer-overrides.
Fix by expanding PCI_VDEVICE() manually, omitting the trailing
.class/.class_mask zeroes so each field is set exactly once.
Found with W=1
