[PATCH 0/6] staging: line6: more checkpatch.pl warnings fixes

[Stefan Hajnoczi]

This series addresses the remaining checkpatch.pl warnings that are easy to
fix.  This takes the line6 driver another step closer to getting merged as an
ALSA driver.

  staging: line6: rename MidiBuffer to avoid CamelCase
  staging: line6: wrap comment to 80 chars in driver.c
  staging: line6: use pr_err() instead of printk(KERN_ERR, ...)

[PATCH 1/6] staging: line6: rename MidiBuffer to avoid CamelCase

[Stefan Hajnoczi]

Fix checkpatch.pl warnings related to MidiBuffer:

  WARNING: Avoid CamelCase: <MidiBuffer>
  #947: FILE: staging/line6/driver.c:363:
  +       struct MidiBuffer *mb = &line6->line6midi->midibuf_in;

Rename MidiBuffer to midi_buffer.

Note that "midibuf" would be another good name but sound/oss/midibuf.c
already uses it for a different concept.  Avoid possible confusion by
using "midi_buffer" instead.
