Currently, pinctrl_register() just returns NULL on error, so the callers can not know the exact reason of the failure. Some of the pinctrl drivers return -EINVAL, some -ENODEV, and some -ENOMEM on error of pinctrl_register(), although the error code might be different from the real cause of the error. This commit reworks pinctrl_register() to return the appropriate error code and modifies all of the pinctrl drivers to use IS_ERR() for the error checking and PTR_ERR() for getting the error code. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com> --- This patch is based on linux-pinctrl/devel (Commit 7164873e7c69d6bab74726debc3b495a86332b1f). I think I converted all of the pinctrl drivers, but just in case, I'd like the driver maintainers to check this patch out. drivers/pinctrl/bcm/pinctrl-bcm281xx.c | 4 ++-- drivers/pinctrl/bcm/pinctrl-bcm2835.c | 4 ++-- drivers/pinctrl/bcm/pinctrl-cygnus-gpio.c | 4 ++-- drivers/pinctrl/bcm/pinctrl-cygnus-mux.c | 4 ++-- drivers/pinctrl/berlin/berlin.c | 4 ++-- drivers/pinctrl/core.c | 17 ++++++++++------- drivers/pinctrl/freescale/pinctrl-imx.c | 4 ++-- drivers/pinctrl/freescale/pinctrl-imx1-core.c | 4 ++-- drivers/pinctrl/freescale/pinctrl-mxs.c | 4 ++-- drivers/pinctrl/intel/pinctrl-cherryview.c | 4 ++-- drivers/pinctrl/intel/pinctrl-intel.c | 4 ++-- drivers/pinctrl/mediatek/pinctrl-mtk-common.c | 4 ++-- drivers/pinctrl/meson/pinctrl-meson.c | 4 ++-- drivers/pinctrl/mvebu/pinctrl-mvebu.c | 4 ++-- drivers/pinctrl/nomadik/pinctrl-abx500.c | 4 ++-- drivers/pinctrl/nomadik/pinctrl-nomadik.c | 4 ++-- drivers/pinctrl/pinctrl-adi2.c | 4 ++-- drivers/pinctrl/pinctrl-amd.c | 4 ++-- drivers/pinctrl/pinctrl-as3722.c | 4 ++-- drivers/pinctrl/pinctrl-at91.c | 4 ++-- drivers/pinctrl/pinctrl-lantiq.c | 4 ++-- drivers/pinctrl/pinctrl-lpc18xx.c | 4 ++-- drivers/pinctrl/pinctrl-palmas.c | 4 ++-- drivers/pinctrl/pinctrl-pistachio.c | 4 ++-- drivers/pinctrl/pinctrl-rockchip.c | 4 ++-- drivers/pinctrl/pinctrl-single.c | 4 ++-- drivers/pinctrl/pinctrl-st.c | 4 ++-- drivers/pinctrl/pinctrl-tb10x.c | 4 ++-- drivers/pinctrl/pinctrl-tegra-xusb.c | 4 ++-- drivers/pinctrl/pinctrl-tegra.c | 4 ++-- drivers/pinctrl/pinctrl-tz1090-pdc.c | 4 ++-- drivers/pinctrl/pinctrl-tz1090.c | 4 ++-- drivers/pinctrl/pinctrl-u300.c | 4 ++-- drivers/pinctrl/pinctrl-zynq.c | 4 ++-- drivers/pinctrl/qcom/pinctrl-msm.c | 4 ++-- drivers/pinctrl/qcom/pinctrl-spmi-gpio.c | 4 ++-- drivers/pinctrl/qcom/pinctrl-spmi-mpp.c | 4 ++-- drivers/pinctrl/samsung/pinctrl-exynos5440.c | 4 ++-- drivers/pinctrl/samsung/pinctrl-samsung.c | 4 ++-- drivers/pinctrl/sh-pfc/pinctrl.c | 4 ++-- drivers/pinctrl/sirf/pinctrl-atlas7.c | 4 ++-- drivers/pinctrl/sirf/pinctrl-sirf.c | 4 ++-- drivers/pinctrl/spear/pinctrl-spear.c | 4 ++-- drivers/pinctrl/sunxi/pinctrl-sunxi.c | 4 ++-- drivers/pinctrl/vt8500/pinctrl-wmt.c | 4 ++-- 45 files changed, 98 insertions(+), 95 deletions(-)
