Subject: delkin_cb: use struct ide_port_info
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=1c4d4ad50ac5cc74c605c4a467db42c961ec7a69;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

delkin_cb: use struct ide_port_info

Convert the driver to use struct ide_port_info - as a nice side-effect
this fixes racy setup of ->io_32bit/unmask settings (after ide_device_add()
call device can be already in use).
