[U-Boot] legacy I2C_GET_BUS()/I2C_SET_BUS() not working anymore

[Dirk Eibach]

Hello Heiko,

your commit 385c9ef5 introduced in include/i2c.h

#if defined(CONFIG_SYS_I2C) || defined(CONFIG_I2C_MULTI_BUS)
# if !defined(CONFIG_SYS_MAX_I2C_BUS)
#  define CONFIG_SYS_MAX_I2C_BUS 2
# endif
# define I2C_MULTI_BUS 0
#else
# define CONFIG_SYS_MAX_I2C_BUS 1
# define I2C_MULTI_BUS 0
#endif

which does not seem to be correct as we end up with I2C_MULTI_BUS set
to 0 in any case.

static inline void I2C_SET_BUS(unsigned int bus)
{
if (I2C_MULTI_BUS)
i2c_set_bus_num(bus);
}

This means that  I2C_GET_BUS()/I2C_SET_BUS() does not work anymore. I
stumbled upon this as we are using these legacy funtions in
controlcenterd (which will be changed in the next mergewindow).

Cheers
Dirk
