commit 04b2d03a upstream. If the SPI bus number is provided by a DT alias, idr_alloc() is called twice, leading to: WARNING: CPU: 1 PID: 1 at drivers/spi/spi.c:2179 spi_register_controller+0x11c/0x5d8 couldn't get idr Fix this by moving the handling of fixed SPI bus numbers up, before the DT handling code fills in ctlr->bus_num.
