3.10-stable review patch. If anyone has any objections, please let me know.
------------------
From: Hans Holmberg <[email protected]>
commit 7b8792bbdffdff3abda704f89c6a45ea97afdc62 upstream.
of_get_named_gpiod_flags fails with -EPROBE_DEFER in cases
where the gpio chip is available and the GPIO translation fails.
This causes drivers to be re-probed erroneusly, and hides the
real problem(i.e. the GPIO number being out of range).

This patch is causing several build failures.
Error log:
drivers/gpio/gpiolib-of.c: In function 'of_gpiochip_find_and_xlate':
drivers/gpio/gpiolib-of.c:50:3: error: implicit declaration of function
'ERR_PTR'
since "#include <linux/err.h>" is missing in drivers/gpio/gpiolib-of.c
in the 3.10 kernel.
Thanks for letting me know, I've pushed out a fix for this in the quilt
tree of patches.
Confirmed; build and qemu tests now pass with no errors.
