bcma: gpio: Use generic_handle_irq_safe()

2022-09-19T13:08:39Z

On PREEMPT_RT enabled kernels the demultiplex interrupt handler is force threaded and runs with interrupts enabled. The invocation of generic_handle_irq() with interrupts enabled triggers a lockdep warning due to a non-irq safe lock acquisition. Instead of disabling interrupts on the driver level, use generic_handle_domain_irq_safe().

bcma: simplify reference to driver name

2021-10-12T22:50:12Z

When bcma_host_pci_probe() is called, the PCI driver core has already assigned the device's driver in local_pci_probe(). So dev->driver is always true, and here it points to bcma_pci_bridge_driver, which has .name set to "bcma-pci-bridge". Simplify accordingly.
