Subject: s390/qdio: use dev_info() in qdio_print_subchannel_info()
Git-commit: f86991b3a95ab245510ccd111926d1f40ae13b91
Patch-mainline: v5.15-rc1
References: jsc#PED-588 bsc#1203836 LTC#198623

Prefer dev_info() over a raw printk. This also adds the device and
driver names into the output, so that we have:

Before:
    qdio: 0.0.17c0 ZFCP on SC 17 using [...]

After:
    zfcp 0.0.17c0: qdio: ZFCP on SC 17 using [...]
