[OpenWrt-Devel] [PATCH] kernel: add gpio-it87

[Florian Eckert]

Since commit 910df3f06cc902ca2cb0ca8e963e9354c930df1a we have build in
on all X86/64 platforms the gpio-it87 driver.

Since this change I am getting the following error message on boot.
 > kern.err kernel: [    1.009416] gpio_it87: no device

I do not have this device on my system. To prevent the nonsensical
message and the loading of the module I have added this as a package, so
that it can be installed later or during image building.
