Subject: swarm: call ide_find_port_slot() later
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=cb8ea0929c9cb899d61c4e155aace0b34d8cffe3;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

swarm: call ide_find_port_slot() later

Move ide_find_port_slot() call closer to ide_device_add().

This is basically a preparation for the future changes.
