$ git blame -L 338,338 drivers/pinctrl/mvebu/pinctrl-dove.c
c9f95ced drivers/pinctrl/pinctrl-dove.c (Sebastian Hesselbarth
2012-09-13 17:41:44 +0200 338)   gcfg2 &= ~(DOVE_TWSI_ENABLE_OPTION2 |
DOVE_TWSI_ENABLE_OPTION2);

$ git tag --contains c9f95ced | grep '^v[23]\.[0-9][0-9]*' | sed -r -e
's/^(v[23]\.[0-9][0-9]*).*$/\1.x/' | sort -uV
v3.7.x
v3.8.x
v3.9.x
v3.10.x
v3.11.x
v3.12.x

so it should get flagged for v3.7 and newer.

Watch out for really old stuff, the regex above doesn't properly handle
v2.6.XX.x...

hth,

Jason.
