3.19.8-ckt9 -stable review patch. If anyone has any objections, please let me know.
------------------
From: Carl Frederik Werner <frederik@cfbw.eu>
commit 3a2fa775bd1d0579113666c1a2e37654a34018a0 upstream.
Let's fix pinmux address of gpio 170 used by tfp410 powerdown-gpio.
According to the OMAP35x Technical Reference Manual CONTROL_PADCONF_I2C3_SDA[15:0] 0x480021C4 mode0: i2c3_sda CONTROL_PADCONF_I2C3_SDA[31:16] 0x480021C4 mode4: gpio_170 the pinmux address of gpio 170 must be 0x480021C6.
The former wrong address broke i2c3 (used by hdmi ddc), resulting in kernel message: omap_i2c 48060000.i2c: controller timed out
