[PATCH] pinctrl: single: avoid to set read only object

[haojian.zhuang@linaro.org (Haojian Zhuang)]

drivers/pinctrl/pinctrl-single.c:1441:3: error: assignment of member
?is_generic? in read-only object
make[2]: *** [drivers/pinctrl/pinctrl-single.o] Error 1

Since pcs_pinconf_ops is changed to read only structure, probe()
function can't set is_generic variable any more. So append new
pcs_pinconf_generic_ops.
