Hans de Goede aac871e493 platform/x86: x86-android-tablets: Fix use after free on platform_device_register() errors 
[ Upstream commit 2fae3129c0 ]

x86_android_tablet_remove() frees the pdevs[] array, so it should not
be used after calling x86_android_tablet_remove().

When platform_device_register() fails, store the pdevs[x] PTR_ERR() value
into the local ret variable before calling x86_android_tablet_remove()
to avoid using pdevs[] after it has been freed.

Fixes: 5eba014120 ("platform/x86: x86-android-tablets: Add support for instantiating platform-devs")
Fixes: e2200d3f26 ("platform/x86: x86-android-tablets: Add gpio_keys support to x86_android_tablet_init()")
