[PATCH -next v2] gpio: GPIO_SCH: depends on LPC_SCH

[PATCH -next v2] gpio: GPIO_SCH: depends on LPC_SCH

[Randy Dunlap]

Since LPC_SCH provides GPIO functionality, GPIO_SCH should depend on
LPC_SCH to prevent kconfig warning and build errors:

WARNING: unmet direct dependencies detected for LPC_SCH
  Depends on [n]: HAS_IOMEM [=y] && PCI [=n]
  Selected by [y]:
  - GPIO_SCH [=y] && GPIOLIB [=y] && X86 [=y] && (X86 [=y] || COMPILE_TEST [=n]) && ACPI [=y]

and

../drivers/mfd/lpc_sch.c:204:1: warning: data definition has no type or storage class
 module_pci_driver(lpc_sch_driver);
 ^~~~~~~~~~~~~~~~~
../drivers/mfd/lpc_sch.c:204:1: error: type defaults to ‘int’ in declaration of ‘module_pci_driver’ [-Werror=implicit-int]

Thanks!

Bart, please, take it in your tree directly, or if you wish I may
collect this one together with Hans' one and send a PR.

Bart, nevermind. Same answer as to Hans' patch: I'll take care as usual.

Pushed to my review and testing queue, thanks!

I have dropped these two since my SoB will be there. But also I think it's
better to narrow down this kind of Cc list as much as possible (for example, we
know that Bart and Linus are maintainers of GPIO, no need to include them
explicitly here, just use --cc parameter when sending).
