[PATCH 0/4] DMA-buf: Fine-tuning for four function implementations

[PATCH 0/4] DMA-buf: Fine-tuning for four function implementations

[SF Markus Elfring]

From: Markus Elfring <elfring@users.sourceforge.net>
Date: Mon, 8 May 2017 11:05:05 +0200

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

Markus Elfring (4):
  Combine two function calls into one in dma_buf_debug_show()
  Improve a size determination in dma_buf_attach()
  Adjust a null pointer check in dma_buf_attach()
  Use seq_putc() in two functions

[PATCH 1/4] dma-buf: Combine two function calls into one in dma_buf_debug_show()

[SF Markus Elfring]

From: Markus Elfring <elfring@users.sourceforge.net>
Date: Mon, 8 May 2017 10:32:44 +0200

A bit of data was put into a sequence by two separate function calls.
Print the same data by a single function call instead.

This issue was detected by using the Coccinelle software.

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

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

Three single characters (line breaks) should be put into a sequence.
Thus use the corresponding function "seq_putc".

This issue was detected by using the Coccinelle software.

[PATCH 4/4] dma-buf: Use seq_putc() in two functions

[SF Markus Elfring]

From: Markus Elfring <elfring@users.sourceforge.net>
Date: Mon, 8 May 2017 10:55:42 +0200

Three single characters (line breaks) should be put into a sequence.
Thus use the corresponding function "seq_putc".

This issue was detected by using the Coccinelle software.

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

Thanks much for your patches; will where them up now.


Markus Elfring (4):
  Combine two function calls into one in dma_buf_debug_show()
  Improve a size determination in dma_buf_attach()
  Adjust a null pointer check in dma_buf_attach()
  Use seq_putc() in two functions
