This patch series irons out checkpatch.pl errors in dvb_dummy_fe.c
and dvb_dummy_fe.h.

These patches were sent previously in a separate fashion, but they
are now compiled into this series

Changes in v3:
As suggested by Sean:
Dropped media: dvb_dummy_fe: Add error messages in case of attach failure

Squashed dvb_dummy_fe: Fix long lines and 
dvb_dummy_frontend: remove 'extern' keyword from declaration with
media: dvb_dummy_fe: Fix ERROR: POINTER_LOCATION

Added a new commit: media: dvb_dummy_fe: Fix ERROR: POINTER_LOCATION

Daniel W. S. Almeida (4):
  media: dvb_dummy_fe: place EXPORT_SYMBOL below corresponding function
  media: dvb_dummy_fe: Fix ERROR: POINTER_LOCATION, AVOID_EXTERN and
    long lines
  media: dvb_dummy_fe: Add blank line after declaration
  media: dvb_dummy_fe: change printk to pr_warn

dvb_dummy_fe.c had all its EXPORT_SYMBOL macros located at the end of the
file. Now these are located directly below the symbol they are exporting
for increased readability.
