From: Sudip Mukherjee @ 2020-04-03 13:43 UTC (permalink / raw)
To: Greg Kroah-Hartman; +Cc: linux-kernel, Joe Perches, Sudip Mukherjee
From: Joe Perches <joe@perches.com>
Eliminate warnings by using pr_debug which is the more typical
kernel debugging style and also enable dynamic_debug on these
outputs.
Miscellaneous:
o A few messages were logged at KERN_INFO when enabled, now KERN_DEBUG
o Convert %d/%d to %zd/%zu to avoid compilation warnings

From: Sudip Mukherjee @ 2020-04-03 13:43 UTC (permalink / raw)
To: Greg Kroah-Hartman; +Cc: linux-kernel, Joe Perches, Sudip Mukherjee
From: Joe Perches <joe@perches.com>
Some of the logging can be poorly formatted because of unexpected
line breaks given printks without KERN_CONT that should be pr_cont.
Miscellanea:
o Remove unnecessary spaces between function name and open parenthesis
o Convert bare printks to pr_<level> where appropriate
o Convert embedded function names to use %s, __func__
o Coalesce formats
o Realign arguments
o Use do {} while (0) in a macro and not a bare if

Now that all the drivers using parallel port has been converted to use
device model, there is no driver left which has devmodel as false.
Remove the part of the code which expects devmodel can be false.
