drivers/misc/ad525x_dpot.c: fix part name typos in defines 2010-10-26T23:52:14+00:00 Michael Hennerich michael.hennerich@analog.com 2010-10-26T21:22:35+00:00 5f400cf40fc703673aa791966ffb1c628c1ff45a There is no runtime effect by this change. It frees up namespace for defines erroneously used. This is required to actually support devices requiring the namespace, added with "drivers/misc/ad525x_dpot.c: new features". All defines touched have the same value defined, after the change.
