[PATCH] [media] pt3: remove bogus module_is_live() check

From: Arnd Bergmann
Date: Mon Sep 29 2014 - 10:29:06 EST

The new pt3 driver checks the module reference for presence
before dropping it, which fails to compile when modules
are disabled:

media/pci/pt3/pt3.c: In function 'pt3_attach_fe':
media/pci/pt3/pt3.c:433:6: error: implicit declaration of function 'module_is_live' [-Werror=implicit-function-declaration]

As far as I can tell however, this check is not needed at all, because
the module will not go away as long as pt3 is holding a reference on
it. Also the previous check for NULL pointer is not needed at all,
because module_put has the same check.
