The bcm2835aux UART driver stores a struct uart_8250_port in its private data even though it's only passed once to serial8250_register_8250_port() (which copies all relevant data) and becomes obsolete afterwards. Allocate the struct on the stack instead for simplicity and to conserve memory. The driver also initializes a spinlock in the struct which is never used. Drop that as well.
