[PATCH v2 3/3] ipmi: Update driver to use 'dev_printk()' and its constructs

Myron Stowe
2010-03-13T18:13:53Z

Update core IPMI driver printk()'s with dev_printk(), and its constructs,
to provide additional device topology information.

An example of the additional device topology for a PNP device -
ipmi_si 00:02: probing via ACPI
ipmi_si 00:02: [io 0x0ca2-0x0ca3] regsize 1 spacing 1 irq 0
ipmi_si 00:02: Found new BMC (man_id: 0x00000b, prod_id: 0x0000, ...
ipmi_si 00:02: IPMI kcs interface initialized

and for a PCI device -
ipmi_si 0000:01:04.6: probing via PCI
ipmi_si 0000:01:04.6: PCI INT A -> GSI 21 (level, low) -> IRQ 21
ipmi_si 0000:01:04.6: [mem 0xf1ef0000-0xf1ef00ff] regsize 1 spaci...
ipmi_si 0000:01:04.6: IPMI kcs interface initialized
