Subject: PCI: sh: use generic pcibios_set_master()
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=dab0311d65715d240989a136a41616853ad72347;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

PCI: sh: use generic pcibios_set_master()

This patch removes sh's architecture-specific 'pcibios_set_master()'
routine and lets the default PCI core based implementation handle PCI
device 'latency timer' setup.

No functional change.
