[PATCH v3 0/5] staging: vme_user: Remove printk's & clean up log messages

[Soumya Negi]

Staging driver vme_user has a bunch of printk() calls in vme.c which
triggers checkpatch warnings. Remove all printk's by either changing
them to the appropriate logging mechanism i.e dev_err()/dev_warn() or
by dropping the unneeded printk's.

Also, clean up the messages further by using __func__ in the string
instead of function names.

This patchset fixes all checkpatch warnings like:

    WARNING: Prefer [subsystem eg: netdev]_err([subsystem]dev, ... then
             dev_err(dev, ... then pr_err(...  to printk(KERN_ERR ...
&
    WARNING: Prefer using '"%s...", __func__' to using 'vme_lm_get',
             this function's name, in a string

Patches must be applied in order.

Changes in v3:
 1. Patch 1: Use only dev_err() to replace printk(). v2 replaced some
    of the printk's using pr_err(). Leave the calls as printk's. New 
    patches added in v3 handle these printk's. 
    (as per feedback from gregkh@xxxxxxxxxxxxxxxxxxx)
 2. Added Patch 3: Remove unneeded printk.
    (suggested by gregkh@xxxxxxxxxxxxxxxxxxx)
 3. Added Patch 4: Remove NULL-checks for bridge device & resource.
    Corresponding printk's(part of the check blocks) are removed too.
    (as per feedback from gregkh@xxxxxxxxxxxxxxxxxxx)
 4. Added Patch 5: Replace printk with dev_err() in vme_check_window()
    Since vme_check_window() doesn't have access to bridge device, pass
    the bridge pointer to it.
    (suggested by gregkh@xxxxxxxxxxxxxxxxxxx) 
 5. Edit cover letter subject & body according to patches added in v3.

Changes in v2:
 1. Correct "cleanup" to "clean up" in cover letter.   (as per feedback
    from julia.lawall@xxxxxxxx)
 2. Patch 1: Change the pr_*() calls used to replace printk's in v1 to 
    dev_*() wherever possible, as it adds more context to the messages.
    (as per feedback from julia.lawall@xxxxxxxx &
