[patch] pda_power: remove unneeded assignment

[Dan Carpenter]

We never use the "ret" value from this assignment, and also
PTR_ERR(NULL) is zero.  I looked at it and this driver is designed to
accept a NULL value for "ac_draw".  So there isn't a bug in the original
code and we can just remove this confusing assignment.
