Can you point me to something? This is the result of git grep, so I odn't see it 
used at all.

arch/blackfin/include/asm/gpio.h:static inline int name_to_gpio(const char 
*name)
arch/blackfin/include/asm/gpio.h:#define name_to_gpio(n) name_to_gpio(n)
common/cmd_gpio.c:#ifndef name_to_gpio
common/cmd_gpio.c:#define name_to_gpio(name) simple_strtoul(name, NULL, 10)
common/cmd_gpio.c:      return name_to_gpio(name);
