My code checkers say something:

    CHECKPATCH
CHECK: usleep_range is preferred over udelay; see 
Documentation/timers/timers-howto.txt
#37: FILE: drivers/i2c/busses/i2c-octeon.c:390:
+                       udelay(50);

CHECK: usleep_range is preferred over udelay; see 
Documentation/timers/timers-howto.txt
#70: FILE: drivers/i2c/busses/i2c-octeon.c:529:
+                       udelay(50);

Dunno if you want to change that? Seems reasonable to me. Also:

    SMATCH
drivers/i2c/busses/i2c-octeon.c:544 octeon_i2c_hlc_wait() warn: inconsistent 
indenting

This is true as well.
