These are called by sa11x0_drv_pcmcia_probe (which is marked now with __devinit) so they can go to .devinit.text now, too. This fixes: WARNING: drivers/pcmcia/sa1100_cs.o(.text+0x10): Section mismatch in reference from the function sa11x0_drv_pcmcia_probe() to the function .init.text:pcmcia_simpad_init() The function sa11x0_drv_pcmcia_probe() references the function __init pcmcia_simpad_init(). This is often because sa11x0_drv_pcmcia_probe lacks a __init annotation or the annotation of pcmcia_simpad_init is wrong. and a similar warning for pcmcia_collie_init, pcmcia_cerf_init, pcmcia_h3600_init and pcmcia_shannon_init. While at it mark pcmcia_assabet_init with __devinit, too.
