[PATCH] staging: media: atomisp: Remove unneeded return statements in irq.c

[Hezekiah Mogere Joseph Mayaka <hmjm081106@gmail.com>]

Remove the bare return statements at the end of void functions, along
with the blank lines before them. They have no effect and checkpatch.pl
warns about them:

  WARNING: void function return statements are not generally useful
