[PATCH 3/3] Input: turbografx - store object in correct index

From: Sudip Mukherjee
Date: Fri Oct 02 2015 - 07:29:07 EST


The variable i is used to check the port to attach to and we are
supposed to save the reference of struct tgfx in the location given by
tgfx_base[i]. But after finding out the index i is getting modified again
so we saved in a wrong index.
