From: David Gow <davidgow@xxxxxxxxxx> commit ba115adf61b36b8c167126425a62b0efc23f72c0 upstream. Make the samsung-keypad driver explicitly depend on CONFIG_HAS_IOMEM, as it calls devm_ioremap(). This prevents compile errors in some configs (e.g, allyesconfig/randconfig under UML): /usr/bin/ld: drivers/input/keyboard/samsung-keypad.o: in function `samsung_keypad_probe': samsung-keypad.c:(.text+0xc60): undefined reference to `devm_ioremap' Signed-off-by: David Gow <davidgow@xxxxxxxxxx> Acked-by: anton ivanov <anton.ivanov@xxxxxxxxxxxxxxxxxx> Link: https://lore.kernel.org/r/20220225041727.1902850-1-davidgow@xxxxxxxxxx Signed-off-by: Dmitry Torokhov <dmitry.torokhov@xxxxxxxxx> Signed-off-by: Greg Kroah-Hartman <gregkh@xxxxxxxxxxxxxxxxxxx> --- drivers/input/keyboard/Kconfig | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) --- a/drivers/input/keyboard/Kconfig +++ b/drivers/input/keyboard/Kconfig @@ -556,7 +556,7 @@ config KEYBOARD_PMIC8XXX config KEYBOARD_SAMSUNG tristate "Samsung keypad support" - depends on HAVE_CLK + depends on HAS_IOMEM && HAVE_CLK select INPUT_MATRIXKMAP help Say Y here if you want to use the keypad on your Samsung mobile Patches currently in stable-queue which might be from davidgow@xxxxxxxxxx are queue-5.16/input-samsung-keypad-properly-state-iomem-dependency.patch
