As per below information

GFP_KERNEL  FLAG

This is a normal allocation and might block. This is the flag to use in
process context code when it is safe to sleep.

GFP_ATOMIC FLAG

The allocation is high-priority and does not sleep. This is the flag to
use in interrupt handlers, bottom halves and other situations where you
cannot sleep

And we can take advantage of GFP_KERNEL , as when system is in low
memory chances of getting success is high compared to GFP_ATOMIC.

As visornic_probe is in  process context we can use GPF_KERNEL.

The linux coding style document states:

  1) That braces should not be used where a single single statement
     will do. Therefore all instances of single block statements
     wrapped in braces that do not meet the qualifications of any
     of the exceptions to the rule should be fixed up.

  2) That the declaration of variables local to a given function
     should be immediately followed by a blank newline. Therefore,
     the single instance of this in kpc2000_i2c.c should be fixed
     up.

All the attribute show call-backs check whether pcard is NULL.  However,
pci_set_drvdata(pdev, pcard) is called before the sysfs files are
created during probe, and pci_set_drvdata(pdev, NULL) is not called
until after they are destroyed during remove; therefore, pcard will not
be NULL, and we can drop the checks.
Signed-off-by: Jeremy Sowden <jeremy@azazel.net>
Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

All the call-backs used the same formula to retrieve the pcard from dev:

  struct pci_dev *pdev = to_pci_dev(dev);
  struct kp2000_device *pcard;

  if (!pdev)
    return NULL;

  pcard = pci_get_drvdata(pdev);

Since to_pci_dev is a wrapper for container_of, it will not return NULL,
and since pci_get_drvdata just calls dev_get_drvdata on the dev member
of pdev, this is equivalent to:

  struct kp2000_device *pcard = dev_get_drvdata(&(container_of(dev, struct pci_dev, dev)->dev));

and we can simplify it to:

  struct kp2000_device *pcard = dev_get_drvdata(dev);

staging: kpc2000: added separate show functions for readable kp device attributes, defined them as read-only, and declared them static.

Defined separate simple show functions for each attribute instead of
having a one big one containing a chain of conditionals.

Replaced calls to scnprintf with sprintf since all the outputs are
single integers.

All the readable device attributes are read-only, so used DEVICE_ATTR_RO
to define them.

The definitions are only used to populate the kp_attr_list attribute
array, so declared them as static.

Fixes the following sparse warnings:

The arcx-anybus's registers are accessed via a memory-mapped
IO region. A regmap associated with this region is created
using custom reg_read() / reg_write() callbacks.

However, an abstraction which creates a memory-mapped IO
region backed regmap already exists: devm_regmap_init_mmio().

Replace the custom regmap with the existing kernel abstraction.
