This patch removes half custom printk macros ERR and replace it with
pr_err, for no appropriate struct device *dev field where found for dev_err.
Issue addressed by checkpathc.pl.

Signed-off-by: Haneen Mohammed <hamohammed.sa@gmail.com>

v6: Justify the use of pr_err instead of dev_err.

Removing the macro would seem like remomving the definition.  Here you are
removing the uses.  That could be more clear.

Are you sure that there is no appropriate field in the nbu2ss_udc
structure?

nbu2ss_udc structure in the following function has a dev field.
 "static void _nbu2ss_dump_register(struct nbu2ss_udc *udc)"
But I thought I can't use dev_err in the following because if udc is
null then udc->dev would be null, so I used pr_err instead.
        if (udc == NULL) {
		pr_err("udc: %s udc == NULL\n", __func__);

Or that is fine and using dev_err(udc->dev, even if udc is null  wouldn't affect the program?

Thanks,

This patch removes  __func__ from dev_err.
dev_err includes the function name in the log printout, so there is no
need to include it manually.

This patchset fixes the following coding style issues found by checkpatch.pl:
Do not add new typedefs.
Use of volatile is usually wrong.
printk(KERNEL_ERR not prefered.

Changes in v9:
- Edit patches commit msg
- Merged two patches into one "the removal of the use of macro"
- Justify the use of pr_err
Changes in v8:
- Edit first patch subject line.
Changes in v7:
- Add missing first patch in v6: removal of typedefs and volatile.
Changes in v6:
- Merged two patches into one: remove typedef and volatile.
- Justified the use of pr_err instead of dev_err.
Changes in v5:
- Fix spelling mistakes
- Justify the removal of volatile
- Replaced pr_err with dev_err when possible
Changes in v4:
- Patchset broken into smaller pathces
Changes in v3:
- Create patchset from two patches
Changes in v2:
- First patch reversion

This patch doesn't apply to my tree, can you refresh the whole series
and resend?

This patch removes the use of custom printk macros ERR and replace it with
dev_err, or pr_err in the following cases:
- if no appropriate struct device *dev field where found for dev_err.
- or dev could be null eg. "dev_err(udc->dev" not possible inside "if (udc == null)"
Issue addressed by checkpathc.pl.

Signed-off-by: Haneen Mohammed <hamohammed.sa@gmail.com>

v9: merged two patches into one, and justify the use of pr_err.

This patch removes  __func__ from dev_err.
dev_err includes the function name in the log printout, so there is no
need to include it manually.
