* gpio: xlp: Convert to use gpiolib irqchip helpersKamlakant Patel2015-10-221-10/+11
| | | | | | | | | | | | | | commit "325f0a (MIPS: Netlogic: Use chip_data for irq_chip methods)" Updates "mips/netlogic/common/irq.c" to use chip_data to store interrupt controller data pointer. Before this commit handler_data was used to store interrupt controller data which caused errors while using gpiochip_set_chained_irqchip. Update XLP GPIO driver to use the gpiolib irqchip helpers. And add missing depends on OF_GPIO in Kconfig. Signed-off-by: Kamlakant Patel <kamlakant.patel@broadcom.com> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
* gpio: xlp: fix error return codeJulia Lawall2015-08-261-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Return a negative error code on failure. A simplified version of the semantic match that finds this problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> @@ identifier ret; expression e1,e2; @@ ( if (\(ret < 0\|ret != 0\)) { ... return ret; } | ret = 0 ) ... when != ret = e1 when != &ret *if(...) { ... when != ret = e2 when forall return ret; } // </smpl> Signed-off-by: Julia Lawall <Julia.Lawall@lip6.fr> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
