Subject: [PATCH 11/17] staging: gpib: ines console messaging cleanup
Enable module name to be printed in pr_xxx and dev_xxx
Use DRV_NAME defined as KBUILD_MODNAME instead of hard coded
string "ines_gpib" in pci_request_regions, request_irq and
request_region.
Remove "ines:" and "ines_gpib:" string prefixes in messages
since module name printing is enabled.
Change pr_err to dev_err where possible.
Remove interrupt warnings.
Remove PCMCIA debug comments, PCMCIA_DEBUG conditional compilation
symbol, the DEBUG macro definition and its uses.
Change pr_debug to dev_dbg.
Remove pr_info
Remove commented printk.
