Subject: [PATCH] m68k: atari: Rename shifter to shifter_st to avoid conflict
When test-compiling the BCM2835 pin control driver on m68k:
In file included from arch/m68k/include/asm/io_mm.h:32:0,
from arch/m68k/include/asm/io.h:8,
from include/linux/io.h:13,
from include/linux/irq.h:20,
from include/linux/gpio/driver.h:7,
from drivers/pinctrl/bcm/pinctrl-bcm2835.c:17:
drivers/pinctrl/bcm/pinctrl-bcm2835.c: In function 'bcm2711_pull_config_set':
arch/m68k/include/asm/atarihw.h:190:22: error: expected identifier or '(' before 'volatile'
# define shifter ((*(volatile struct SHIFTER *)SHF_BAS))
"shifter" is a too generic name for a global definition.
As the corresponding definition for Atari TT is already called
"shifter_tt", fix this by renaming the definition for Atari ST to
"shifter_st".

To be queued in the m68k tree for v5.4.
