[PATCH] tinydrm: mipi-dbi: Use seq_putc() in mipi_dbi_debugfs_command_show()

[SF Markus Elfring]

From: Markus Elfring <elfring@users.sourceforge.net>
Date: Mon, 8 May 2017 13:42:03 +0200

A single character (line break) should be put into a sequence.
Thus use the corresponding function "seq_putc".

This issue was detected by using the Coccinelle software.

Markus, I know this is hard for you,
but think more before sending patches.

Use the %p<foo> extensions.

		seq_printf(m, "%*phN\n", len, val)

[PATCH] tinydrm: mipi-dbi: Adjust buffer output in mipi_dbi_debugfs_command_show()

[SF Markus Elfring]

From: Markus Elfring <elfring@users.sourceforge.net>
Date: Wed, 10 May 2017 17:03:20 +0200

* Use a special format string specification for the desired output of the
  array "val" into a sequence.

* Adjust two local variables accordingly.

This refactoring supersedes the update suggestion "tinydrm: mipi-dbi:
