If anyone has any objections, please let me know. ------------------ From: Sai Teja Aluvala [ Upstream commit 1465494e8d07426fa41c0021530cccb2a1ac38fa ] Reset shared Bluetooth hardware after mapping the BAR and before setting up MSI-X interrupts, so stale device state is cleared before IRQ handlers and interrupt masks are configured. Propagate reset errors so probe aborts rather than continuing when the reset fails.
