[PATCH] PCI: amlogic: fix build failure due to missing linux/gpio/consumer.h header

[PATCH] PCI: amlogic: fix build failure due to missing linux/gpio/consumer.h header

[Corentin Labbe]

When building on x86, I got the following build failure:
drivers/pci/controller/dwc/pci-meson.c: In function ‘meson_pcie_assert_reset’:
drivers/pci/controller/dwc/pci-meson.c:290:2: error: implicit declaration of function ‘gpiod_set_value_cansleep’; did you mean ‘gpio_set_value_cansleep’? [-Werror=implicit-function-declaration]
  gpiod_set_value_cansleep(mp->reset_gpio, 0);

                                                ^~~~~~~~~~~~~
                                                GPIOF_INIT_LOW

This is due to the missing linux/gpio/consumer.h header

Hi,

what tree are you testing on and which config ?

Thanks,

I use the next-20190102 tree
The config can be found at http://kernel.montjoie.ovh/configs/x86

Ok, right, it is a config that unfortunately the bots failed to test, I
will pick this up and send it to Bjorn for -rc2 (given that the PCI tree
is not in mainline yet).
