Re: [pinctrl:devel 16/46] drivers/pinctrl/bcm/pinctrl-bcm2835.c:995:10: error: incompatible types when assigning to type 'volatile struct SHIFTER' from type 'unsigned int'

Hi Geert,

could be renamed shifter_st, I suppose. Only used in 
arch/m68k/atari/config.c and drivers/video/fbdev/atafb.c.

Cheers,
