The i2c_client structure can be fairly large, which leads to
a warning about possible kernel stack overflow in some
configurations:
drivers/char/ipmi/ipmb_dev_int.c:115:16: error: stack frame size of 1032 bytes in function 'ipmb_write' [-Werror,-Wframe-larger-than=]
There is no real reason to even declare an i2c_client, as we can simply
call i2c_smbus_xfer() directly instead of the i2c_smbus_write_block_data()
wrapper.
Convert the ipmb_write() to use an open-coded i2c_smbus_write_block_data()
here, without changing the behavior.
It seems that there is another problem with this implementation;
when user space passes a length of more than I2C_SMBUS_BLOCK_MAX
bytes, all the rest is silently ignored. This should probably be
addressed in a separate patch, but I don't know what the intended
behavior is here.
