[PATCH V3 05/19] OMAP3+: voltage: use IS_ERR_OR_NULL

From: nm@ti.com (Nishanth Menon)
Date: 2011-03-05 15:29:08
Also in: linux-omap
Subsystem: arm port, omap2+ support, the rest · Maintainers: Russell King, Aaro Koskinen, Andreas Kemnade, Kevin Hilman, Roger Quadros, Tony Lindgren, Linus Torvalds 

Use IS_ERR_OR_NULL macro instead of !xyz || IS_ERR(xyz) usage.
