I went through the commits from that time period and identified
possible candidates:

svn commit: r188755 - head/sys/dev/ata

 Remove unused variable.

svn commit: r188761 - in stable/7: lib/libc lib/libc/string
lib/libc/sys sys sys/contrib/pf sys/dev/ath/ath_hal sys/d\
ev/cxgb sys/kern sys/net sys/netinet sys/netinet6 sys/sys

r188144:
    Standardize the various prison_foo_ip[46] functions and prison_if to
    return zero on success and an error code otherwise.  The possible errors
    are EADDRNOTAVAIL if an address being checked for doesn't match the
    prison, and EAFNOSUPPORT if the prison doesn't have any addresses in
    that address family.  For most callers of these functions, use the
    returned error code instead of e.g. a hard-coded EADDRNOTAVAIL or
    EINVAL.


svn commit: r188763 - head/sys/dev/ata
 Make ch->dma.free() called symmetrically to ch->dma.alloc().

svn commit: r188765 - in head/sys/dev/ata: . chipsets

Log:
 As soon as they called in only same one place (ata_pcichannel_attach()),
 join allocate() and dmainit() atapci subdriver's channel initialization
 methods into single ch_attach() method.



 As opposite to ch_attach() add new ch_detach() method to deallocate/disable
 channel.

svn commit: r188743 - head/sys/dev/aac
Log:
 Use outbound message register 0 instead of mailbox 7 in
 aac_{rx,rkt}_get_fwstatus, as done in Adaptec's vendor driver as well as
 the Linux drivers.
