Applied to for-next, thanks!
I can recommend using --strict with checkpatch. It found some issues:
total: 0 errors, 0 warnings, 18 checks, 427 lines checked
CHECK: No space is necessary after a cast
#327: FILE: drivers/i2c/busses/i2c-octeon.c:563:
+ ext |= (u64) msgs[0].buf[0] << SW_TWSI_IA_SHIFT;
I fixed all 14 of those.
CHECK: braces {} should be used on all arms of this statement
#325: FILE: drivers/i2c/busses/i2c-octeon.c:561:
+ if (msgs[0].len == 2) {
[...]
+ } else
[...]
and 2 of those.
