If anyone has any objections, please let me know. ------------------ From: Ray Jui commit 091c531b09c151c2d712a8f347009ca3698a2467 upstream. Since commit 44a7185c2ae6 ("of/platform: Add common method to populate default bus"), ARM64 platform devices are populated at the arch_initcall_sync level; as a result, the platform_driver_probe calls in both the iProc and NSP GPIO drivers fail with -ENODEV since by that time the platform device was not yet registered. Replace platform_driver_probe with platform_driver_register, that allow the device to be register later Fixes: 44a7185c2ae6 ("of/platform: Add common method to populate default bus") Signed-off-by: Ray Jui Tested-by: Eric Anholt Signed-off-by: Linus Walleij Signed-off-by: Greg Kroah-Hartman --- drivers/pinctrl/bcm/pinctrl-iproc-gpio.c | 2 +- drivers/pinctrl/bcm/pinctrl-nsp-gpio.c | 2 +- 2 files changed, 2 insertions(+), 2 deletions(-) --- a/drivers/pinctrl/bcm/pinctrl-iproc-gpio.c +++ b/drivers/pinctrl/bcm/pinctrl-iproc-gpio.c @@ -844,6 +844,6 @@ static struct platform_driver iproc_gpio static int __init iproc_gpio_init(void) { - return platform_driver_probe(&iproc_gpio_driver, iproc_gpio_probe); + return platform_driver_register(&iproc_gpio_driver); } arch_initcall_sync(iproc_gpio_init); --- a/drivers/pinctrl/bcm/pinctrl-nsp-gpio.c +++ b/drivers/pinctrl/bcm/pinctrl-nsp-gpio.c @@ -741,6 +741,6 @@ static struct platform_driver nsp_gpio_d static int __init nsp_gpio_init(void) { - return platform_driver_probe(&nsp_gpio_driver, nsp_gpio_probe); + return platform_driver_register(&nsp_gpio_driver); } arch_initcall_sync(nsp_gpio_init);
