pinctrl: axp209: Fix NULL pointer dereference after allocation
axp20x_build_funcs_groups allocates groups via devm_kcalloc and tries to dereference without checking for NULL. This patch avoids such a scenario. Signed-off-by: Aditya Pakki <pakki001@umn.edu> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
