[PATCH 0/2] apparmorfs: Fine-tuning for three function implementations

From: Markus Elfring <redacted>
Date: Sun, 7 May 2017 13:58:08 +0200

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

Markus Elfring (2):
  Combine two function calls into one in aa_fs_seq_raw_abi_show()
  Use seq_putc() in two functions

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

Two 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.
