Enable module name to be printed in pr_xxx and dev_xxx Use DRV_NAME defined as KBUILD_MODNAME instead of hard coded string "tnt4882_gpib" in pci_driver struct, request_region and request_irq. Remove unsupported chipset pr_err's Remove messages on interrupted or timed out reads and writes. Remove board not found messages and return -ENODEV Remove "tnt4882:" prefix in messages as it will be printed by pr_fmt and dev_fmt. Change pr_err to dev_err where possible. Remove irq and chipset pr_info's. Replace error messages with appropriate error returns. Remove call to mite_list_devices() and the function in mite.c Remove PCMCIA debug comments, PCMCIA_DEBUG conditional compilation symbol, the DEBUG macro definition and its uses. Remove pr_info's in mite.c Signed-off-by: Dave Penkler <dpenkler@xxxxxxxxx> --- drivers/staging/gpib/tnt4882/mite.c | 17 -- drivers/staging/gpib/tnt4882/tnt4882_gpib.c | 186 +++++++------------- 2 files changed, 60 insertions(+), 143 deletions(-) diff --git a/drivers/staging/gpib/tnt4882/mite.c b/drivers/staging/gpib/tnt4882/mite.c index ea64dde46bcb..847b96f411bd 100644 --- a/drivers/staging/gpib/tnt4882/mite.c +++ b/drivers/staging/gpib/tnt4882/mite.c @@ -88,7 +88,6 @@ int mite_setup(struct mite_struct *mite) pr_err("mite: failed to remap mite io memory address.\n");
