[PATCH] firewire: core: typecast from gfp_t to bool more safely

From: Stefan Richter
Date: Sun Apr 28 2013 - 18:16:29 EST

An idr related patch introduced the following sparse warning:
drivers/firewire/core-cdev.c:488:33: warning: incorrect type in initializer (different base types)
drivers/firewire/core-cdev.c:488:33: expected bool [unsigned] [usertype] preload
drivers/firewire/core-cdev.c:488:33: got restricted gfp_t
So let's convert from gfp_t bitfield to Boolean explicitly and safely.
