Minor bug fixes to i2c-pasemi
* Last write during i2c_xfer is of the wrong byte (off-by-1). * Read length is wrong for some of the reads (mistakenly used the PEC version) Signed-off-by: Olof Johansson <olof@lixom.net> Signed-off-by: Jean Delvare <khali@linux-fr.org> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
