[Qemu-devel] [PATCH 1/2] omap_i2c: Clear SBD bit in STAT register on DATA read

[Andreas Färber]

After reading a single-byte I2C response such as the tmp105's response
to 0x01 0x00, the SBD status bit would not get reset on next read, still
indicating validity of only a single byte. Clear it on next word read.
