[PATCH 0/3] mfd/sm501: Adjustments for five function implementations

[SF Markus Elfring]

From: Markus Elfring <elfring@users.sourceforge.net>
Date: Mon, 15 Jan 2018 16:11:22 +0100

Two update suggestions were taken into account
from static source code analysis.

Markus Elfring (3):
  Delete an error message for a failed memory allocation in two functions
  Improve a size determination in two functions
  Adjust 12 checks for null pointers

[SF Markus Elfring]

From: Markus Elfring <elfring@users.sourceforge.net>

Omit an extra message for a memory allocation failure in these functions.

This issue was detected by using the Coccinelle software.

[PATCH 2/3] mfd/sm501: Improve a size determination in two functions

[SF Markus Elfring]

From: Markus Elfring <elfring@users.sourceforge.net>
Date: Mon, 15 Jan 2018 15:47:03 +0100

Replace the specification of data structures by pointer dereferences
as the parameter for the operator "sizeof" to make the corresponding size
determination a bit safer according to the Linux coding style convention.

This issue was detected by using the Coccinelle software.

The script “checkpatch.pl” pointed information out like the following.

Comparison to NULL could be written …

Thus fix the affected source code places.

This change possibility partly depends on the update step
“[PATCH 2/3] mfd/sm501: Improve a size determination in two functions”

> Please rebase and resend.

Do you find the proposed source code transformation generally acceptable?

Markus
