This is not the case with printk(KERN_DEBUG). If you want to know more about dynamic debug, you can read [1]. > diff --git a/drivers/mtd/nand/r852.c b/drivers/mtd/nand/r852.c > index fc9287a..cd3cd1c 100644 > --- a/drivers/mtd/nand/r852.c > +++ b/drivers/mtd/nand/r852.c > @@ -7,6 +7,9 @@ > * published by the Free Software Foundation. > */ > > +#define DRV_NAME "r852" > +#define pr_fmt(fmt) DRV_NAME fmt It would be nicer with: #define pr_fmt(fmt) DRV_NAME ": " fmt ... > + > #include <linux/kernel.h> > #include <linux/module.h> > #include <linux/jiffies.h> > @@ -935,7 +938,7 @@ static int r852_probe(struct pci_dev *pci_dev, const struct pci_device_id *id) > &dev->card_detect_work, 0); > > > - printk(KERN_NOTICE DRV_NAME ": driver loaded successfully\n"); > + pr_notice(": driver loaded successfully\n"); and then pr_notice("driver loaded successfully\n"); > return 0; > > error10: > diff --git a/drivers/mtd/nand/r852.h b/drivers/mtd/nand/r852.h > index 8713c57..709eced 100644 > --- a/drivers/mtd/nand/r852.h > +++ b/drivers/mtd/nand/r852.h > @@ -145,16 +145,16 @@ struct r852_device { > }; > > #define DRV_NAME "r852" You don't need this definition anymore, it's been moved to the .c file.

The only file including r852.h is r852.c, and pr_fmt() has been defined before all include directives, so when the preprocessor reaches this point pr_fmt() already has a valid definition. > > #define dbg(format, ...) \ > if (debug) \ > - printk(KERN_DEBUG DRV_NAME ": " format "\n", ## __VA_ARGS__) > + pr_debug(": " format "\n", ## __VA_ARGS__) > > #define dbg_verbose(format, ...) \ > if (debug > 1) \ > - printk(KERN_DEBUG DRV_NAME ": " format "\n", ## __VA_ARGS__) > + pr_debug(": " format "\n", ## __VA_ARGS__) With the pr_fmt() definition modified as suggested it should be: pr_debug(format "\n", ## __VA_ARGS__) Regards, Boris [1]https://01.org/linuxgraphics/gfx-docs/drm/admin-guide/dynamic-debug-howto.html

Actually pr_debug() shouldn't be used here. We usually don't prefer pr_debug for drivers, instead we use dev_dbg. But as Boris told me that it will be better to first having changed all printks to pr_*() macro and then think about dev_*() macros. > :-) > > </bike-shedding> > > Thanks, > //richard

BTW, I see a bunch of remaining printks when I do 'git grep printk drivers/mtd/nand', basically all those that don't have a KERN_<LOGLEVEL> in it. I know your commit log explicitly says that only printks embedding a log level are converted to pr_xxx(), but it's probably worth patching those printks as well (choosing the appropriate log level between info, err and warn and use pr_xxx() helpers). This should be done in a separate patch of course. > > > :-) > > > > </bike-shedding> > > > > Thanks, > > //richard

The log levels embedded with the name are more concise than printk. Replace printks having a log level with the appropriate pr_*macro. Define pr_fmt() and remove other additional macros from some of the replaced printks. Signed-off-by: Shreeya Patel <shreeya.patel23498@gmail.com> --- Changes in v2 -Merge previous patches of the patchset regarding replacement of printk with pr_*macro, into single patch. Changes in v3 -Define pr_fmt() and remove other additional macros from some of the replaced printks. Also add some more changed printks to pr_*() macro into the patch. drivers/mtd/nand/ams-delta.c | 4 +-- drivers/mtd/nand/cafe_nand.c | 4 +-- drivers/mtd/nand/cs553x_nand.c | 9 ++--- drivers/mtd/nand/diskonchip.c | 76 +++++++++++++++++++++------------------- drivers/mtd/nand/fsl_elbc_nand.c | 4 +-- drivers/mtd/nand/fsl_ifc_nand.c | 2 +- drivers/mtd/nand/mxc_nand.c | 2 +- drivers/mtd/nand/nand_bch.c | 12 +++---- drivers/mtd/nand/nandsim.c | 15 ++++---- drivers/mtd/nand/r852.c | 5 ++- drivers/mtd/nand/r852.h | 8 ++--- drivers/mtd/nand/sh_flctl.c | 2 +- drivers/mtd/nand/sm_common.c | 5 ++- 13 files changed, 77 insertions(+), 71 deletions(-)
