Subject: PNP: use dev_info() in system driver
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=b933e19d32edce2f310dfe0fd943e32ff9798b60;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

PNP: use dev_info() in system driver

Use dev_info() for a little consistency.  Changes this:

    pnp: 00:01: ioport range 0xf50-0xf58 has been reserved
    pnp: 00:01: ioport range 0x408-0x40f has been reserved
    pnp: 00:01: ioport range 0x900-0x903 has been reserved

to this:

    system 00:01: ioport range 0xf50-0xf58 has been reserved
    system 00:01: ioport range 0x408-0x40f has been reserved
    system 00:01: ioport range 0x900-0x903 has been reserved
