Subject: RE: linux-next: build failure after merge of the pinctrl tree

Hi Stephen/Linus,

The patch " [PATCH v2 5/7] gpio: Rename func/macro/var to IP-block,iproc" 
(https://lkml.org/lkml/2015/11/18/1004) in "for-next" and "devel" of  pinctrl
tree ( http://git.linaro.org/people/linus.walleij/linux-pinctrl.git ) has little rebase issue.

Original patch has:
<snip>
-static void cygnus_gpio_unregister_pinconf(struct cygnus_gpio *chip)
+static void iproc_gpio_unregister_pinconf(struct iproc_gpio *chip)
<snip>

while "for-next" and "devel" branch of pinctrl tree has:
<snip>
-static void cygnus_gpio_unregister_pinconf(struct cygnus_gpio *chip)
+static void iproc_gpio_unregister_pinconf(struct cygnus_gpio *chip) 
<snip>

Please suggest us how could we fix this issue.

Regards,
Pramod
