Subject: PCI: rpaphp: refactor tail call to rpaphp_register_slot()
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=6f79eb749df7f1eea76c947f31603ade7d2b5f6d;p=GitHub%2FLineageOS%2Fandroid_kernel_samsung_universal7580.git

PCI: rpaphp: refactor tail call to rpaphp_register_slot()

Eliminate the tail call to rpaphp_register_slot()
by placing it in the caller. This will help later
dis-entanglement.
