Subject: Staging: ipack/bridges/tpci200: remove tpci200_slot_unregister
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=daf8007c02558a61a27ba035844787269406274e;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

Staging: ipack/bridges/tpci200: remove tpci200_slot_unregister

It is not needed as the IP module should free its IRQ using
tpci200_free_irq callback.
