platform/x86: x86-android-tablets: Fix keyboard touchscreen on Lenovo Yogabook1 X90
After commit 4014ae236b1d ("platform/x86: x86-android-tablets: Stop using
gpiolib private APIs") the touchscreen in the keyboard half of
the Lenovo Yogabook1 X90 stopped working with the following error:
Goodix-TS i2c-goodix_ts: error -EBUSY: Failed to get irq GPIO
The problem is that when getting the IRQ for instantiated i2c_client-s
from a GPIO (rather then using an IRQ directly from the IOAPIC),
x86_acpi_irq_helper_get() now properly requests the GPIO, which disallows
other drivers from requesting it. Normally this is a good thing, but
the goodix touchscreen also uses the IRQ as an output during reset
to select which of its 2 possible I2C addresses should be used.
Add a new free_gpio flag to struct x86_acpi_irq_data to deal with this
and release the GPIO after getting the IRQ in this special case.
