The current I2C error handling logic makes static analyzers
confused, and it doesn't follow the coding style we're using:

	drivers/media/i2c/ir-kbd-i2c.c:180 get_key_pixelview() error: uninitialized symbol 'b'.
	drivers/media/i2c/ir-kbd-i2c.c:224 get_key_knc1() error: uninitialized symbol 'b'.
	drivers/media/i2c/ir-kbd-i2c.c:226 get_key_knc1() error: uninitialized symbol 'b'.
